Description of the Invention: [Technical Field of the Invention] The present invention relates to an artificial stone obtained by solidifying a soil such as dredged soil with a binder, and a method for producing the same. [Prior Art] The soft soil represented by dredged soil occurs with dredging and various civil constructions. Among them, the sand-like useful material for civil engineering materials can be directly used in shallow bottoms and buried, etc., but in the case of mud with a high ratio of mud accumulation, there are many substances in the hydrated state, and It is almost impossible to expect the intensity of the soil, so it becomes waste. In order to effectively use the soil, various technologies have been proposed and implemented since the past. Its most representative is to improve the characteristics of the soil, using the same technology as the good soil. For example, in the "Method of Treating Soft Soil with Calcium Stabilization" by the Japan Lime Association (Kashima Publishing House), various techniques for adding cement and lime to the soil to improve the characteristics of the foundation are shown. Further, in Patent Document 1, a technique for mixing steel slag in a dredged soil to improve strength is shown. In this technique, the CaO component of the steel slag is mainly subjected to a hardening reaction of Si, A1, etc. of the dredged soil. The strength of the dredged soil is upgraded. Further, Patent Document 2 discloses a technique of adding a converter slag containing pulverized free CaO and blast furnace cement to a soft soil to perform a curing treatment (improving strength). However, these methods improve the characteristics of the soil material, and are not the performance intensity 'definitely limited to the use of soil. 100119512 3 201209013 On the other hand, Patent Document 3 discloses a method of mixing a solidified material composed of blast furnace slag, quicklime, fly ash, etc. in a dredged soil and solidifying it to obtain a bulk (cured body). In this method, a solidified material of about 40 to 60 parts by mass is added to the dredged soil containing water, and the kneaded material is solidified to produce a bulk material. [PRIOR ART DOCUMENT] [Patent Document] [Patent Document] Japanese Patent Laid-Open Publication No. 2009-121167 [Patent Document 2] Japanese Patent Laid-Open Publication No. Hei. No. 2006-231208 (Patent Document 3) SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) Concrete materials (blocks) are suitable for subsea blocks and the like which require stability because of their large specific gravity. However, on the other hand, when it is applied to a block such as a soft foundation, it has a problem that the foundation sinks and becomes incapable of functioning. Further, the smaller the specific gravity of the inner lining material of the concrete, the smaller the pressure applied to the wall, and therefore the economical efficiency of the entire construction body is high, so it is desirable to be as light as possible. In this regard, in the method of Patent Document 3, a lightweight bulk material having an apparent density of about 5.65 g/cm can be produced. However, since the bone material is not used at all, long-term durability and volume stability cannot be expected, and the monthly bHw which is damaged during use can be expected. Further, the block strength obtained by the method of Patent Document 3 is about 6 N/mm or so, and the maximum is about 8 N/mm 2 . In the use of 100119512 201209013 instead of stone and coagulation, the soil must be JIS-A-5006: 1995 (cut chestnut) -y- 乂 strength (9.8N/mm2 or more). However, the strength of the starting material obtained in Patent Document 3 is the lowest quality soft stone (less than 8 N/mm). 'While the degree of improvement compared to the soil material is a relatively high degree X is used for various purposes as an alternative stone and concrete material. Medium is not sufficient strength. Therefore, the object of the present invention is to solve the problems of the prior art as described above, and to provide an artificial stone which can use a large amount of soil such as dredged soil as a material, and which has a strength above quasi-hard rock and is lighter than concrete. Further, another object of the present invention is to provide a manufacturing method capable of stably producing such an artificial stone. (Means for Solving the Problem) The inventors of the present invention have focused on the lightness of soil such as dredged soil, and have repeatedly reviewed the results of the above problems, and found that the use of soil slag as an aggregate is further added to the soil and the binder. When the material is mixed, a stone (hydrated hardened body) having a strength higher than the quasi-hard stone and lighter than the concrete can be obtained. The present invention has been completed on the basis of such findings, and the following are the gist thereof. [1] A lightweight artificial stone which is a hydrated hardened body obtained by hydrating and hardening a kneaded material containing a mixture of a soil, a binder and a powdery steel slag, and has a mass per unit volume of 2000 to 2200 kg. /m3. [2] The lightweight artificial stone according to [1] above, wherein the uniaxial compressive strength after aging on the 28th is 15 N/mm2 or more. 100119512 5 201209013 [3] The lightweight artificial stone according to the above Π] or [2], wherein the adhesive material contains 80 to 95% by mass of the blast furnace slag micropowder, and the residual portion is made of ordinary Portland cement, lime powder, More than one of the selected types of slaked lime and blast furnace cement. [4] The lightweight artificial stone according to the above [1] or [2], wherein the adhesive material contains 80 to 95% by mass of the blast furnace slag fine powder and fly ash, and the residual portion is made of ordinary Portland cement and lime. The powder, the slaked lime, and the blast furnace cement are selected from the above-mentioned species, and the fly ash is 30% by mass or less of the blast furnace slag fine powder. [5] The lightweight artificial stone according to any one of the above-mentioned items, wherein the steel slag is smelted into a pulverization ratio of 2.5% by mass or more of free Ca slag containing 5% by mass or more. A method for producing a lightweight artificial stone according to any one of the above [1] to [5], which is characterized in that the water content ratio is The soil, the binder and the granular steel of 180~250 are melted, and the proportion of the soil relative to the soil, the binder and the granular steel slag is 4〇555% by volume, and the amount of the steel slag is The mixed material was mixed at 75 〇kg/m3 per volume, and the mixed material was kneaded and the mixture was hydrated and hardened. [7] [7] The method for producing a lightweight artificial stone according to the above [6], wherein the dredged soil generated by the dredging project is used, and the liquid soil stored in the dredged soil is used as the soil. Shu W0 month double wood j The artificial stone of the invention can be effectively utilized because it can use a large amount of dredged soil and other corpses. And it has the strength of quasi-hard rock. The concrete is lighter. Therefore, it is particularly useful in stone applications requiring strength, longevity and light weight. Further, according to the manufacturing method of the present invention, such artificial stone can be stably produced. [Complex application method] The artificial stone material of the present invention is a hydrated hardened body obtained by hydrating and hardening a kneaded material containing a mixed material of clay, a binder and a powdery steel slag, and the mass per unit volume is 2000~ 2200kg/cm3. The inventors of the present invention have also examined the blending conditions for the strength of the hydrated hardened body (hereinafter sometimes referred to as "solidified body") using the dredged soil as a material in Dali. First, the inventors of the present invention have produced a blast furnace slag fine powder and an alkali stimulating agent as a solidified body of a sticky material only in a dredged soil, but have a small specific gravity and are easily cracked by impact, and only a brittle solidified body is obtained. In particular, if the proportion of the dredged soil is increased, the whole becomes a powdery mass, which is weakened by the addition of brittleness and wear, and the stability of the stone cannot be expected because it is too light. Then, the inventors of the present invention have produced a cured body which is further added with natural crushed stone and natural and as an aggregate. However, the mass per unit volume of this condition is 2000 kg/m3 or more. If it is desired to produce a quasi-hard rock, the ratio of the dredged soil in the mixed material is reduced to less than 35 vol%. Figure 1 shows the solidified body obtained from the mixture of the dredged soil and the binder (blast furnace slag micropowder + irritant) and the natural crushed stone and natural sand of the aggregate. The ratio of the dredged soil in the mixed material The relationship with the mass per unit volume of the solidified body 100119512 7 201209013. Of course, such a solidified body (artificial stone) can also be referred to as having usefulness as a material, but the use amount of the dredged soil is insufficient when it is utilized from the viewpoint of effectively utilizing the dredged soil. The inventors of the present invention further reviewed the countermeasures for solving the above problems, and reviewed several major aggregates and further repeated the trials. However, in the course of the evaluation, the strength of the cured body was judged to be slightly lower than the strength expected from the addition of the blast furnace slag fine powder and the stimulating agent. That is, even if the material (aggregate) having a large mixing ratio is simply used, the judgment cannot express the strength of the prediction. Then, the inventors of the present invention conducted a review of the cause, and as a result, it was judged that since the dredged soil has an action of adsorbing alkali, it has a possibility of inhibiting the hardening reaction of the basic reaction of solidification of the cement and the blast furnace slag. The inventors of the present invention have found that a solidified body having a stable strength and specific gravity can be produced by the above-described method, and as a result of further review, it is judged that the steel slag is blended as the aggregate. In Fig. 2, the strength of a solidified body produced using natural crushed stone, natural sand, and steel slag as aggregates, respectively, is shown. In this manufacturing test, the proportion of the mixed material using the dredged soil is 50% by volume, and the amount of the aggregate is 25% by volume (natural gravel, natural sand: about 660 kg/m3, steel slag: about 800 kg/m3), The blast furnace slag fine powder and the alkali stimulating agent (ordinary Portland cement) are used as the binder. Further, as the steel slag, the converter decarburization slag is used for steam curing and stabilization. According to Fig. 2, the solidified body of the steel slag is used for the aggregate, and the solid body of the natural crushed stone or the natural sand is used to exhibit high strength compared to the aggregate. Although the reason is not necessarily clear, it is considered as follows. which is,

: 1995所規定之 相當準硬石以上，即28日熟化後之單軸壓縮強度為 9.8N/mm2以上即可。又，天然石材為強度安定，但在固化 體的情況則根據配合條件發生偏差等，故28日熟化後的單 轴壓縮強度為15N/mm2以上為更佳。 本發明所用之泥土，以疏浚土為代表例，除此以外，例如， 可列舉由挖掘工程所產生的泥、建設污泥等。此處，所謂泥 土，係指一般無法堆積，且顯示出人無法步行於其上之流動

況’可謂為特別有用。 如後述般，泥土於混合材料中以40容積％以上的比例使 用。 作為黏合材，可列舉高爐熔渣微粉末、添加鹼刺激劑的高 爐熔渣微粉末、高爐水泥、普通波特蘭水泥等，且可使用該 等之1種以上。 又，由儘可能不使用天然資材以減輕環境負荷的觀點而 言，更且由確保固化體強度及製造成本的觀點而言，期望於 高爐熔渣微粉末中添加鹼刺激劑作為黏合材。經由使用高爐 熔渣微粉末及驗刺激劑作為黏合材，則可作成鹼環境，發揮 高爐熔渣微粉末的水硬性。即，可促進高爐熔渣微粉末的水 合反應，確保固化體的強度。又，於黏合材使用普通波特蘭 水泥之情況，固化體浸潰於水時的pH上升，比使用高爐熔 渣微粉末及鹼刺激劑的情況更大。因此，於考慮對於周邊環 境的負荷時，使用高爐炫渣微粉末及驗刺激劑為合適。 作為驗刺激劑’可使用例如，石灰粉、消石灰、普通波特 100119512 10 201209013 蘭水泥、咼爐水泥等之丨種以上。此時，含有高爐熔渣微粉 末80〜95質量％ ’且殘餘部分係由石灰粉、消石灰、普通波 特蘭水泥、高爐水泥中選出1種以上為佳。使用高爐熔渣微 粉末及驗刺激劑作為黏合材之情況，若高爐熔渣微粉末的比 例為80質量％以上’則在固化體中不會殘存剩餘的鹼成分。 因此，在海中使用固化體時，鹼對於海水環境的負荷小。又， 於經濟上亦為有利。另一方面，即使高爐熔渣微粉末的比例 超過95質量％亦可混練•固化。但是，若為95質量％以下 則因可輕易安定分散、因疏浚土雜抑制效果使刺激劑的效 果變小’故添加高爐炫錄粉末的效果高，不必使用多樣的 原料’且不會成為設備負擔，因此具有經濟的妥當性。 月材之t鋼查種類’並無特別限定，可列舉熔鐵預處理 嫁渔(脫雜渣、脫魏渣、脫硫㈣等）、轉爐脫碳炼渣、

又’製鋼料的組成亦無特別限制。但，驗度(鳴〇2) 100119512 201209013 咼者則&尚強度的效果變大故為佳。但，若過高則如後述 般，游離CaO的殘存量易變大。又，在過高鹼度之情況， 右以蒸氣熟化等事先施行製鋼熔渣的安定化處理，則變成無 基本的問題，但以熟化處理則有變成粉狀的傾向，故難以確 保發揮作為骨材作用的粒度，更且，游離CaO的内在量亦 增加，故產生熟化時間必須比通常更長，有時内部殘存游離 CaO且體積安定性的偏差變大。因此，鹼度(Ca〇/Si〇2)為 2.0〜5.0左右為佳。 又，以製鋼步驟所生成的炼渣含有〇5質量％以上游離 CaO之情況’將此製鋼熔渣熟化作成粉化率2.5%以下，使 用作為本發明之材料（骨材）為佳。關於驗度較高的溶渣，游 離CaO殘留多。游離CaO經由與水接觸迅速變成ca(OH)2, 具有易離子化並參與反應的優點。但是，另一方面，於熔渣 粒子内部殘存的游離CaO，與浸透之水接觸時膨脹，於粒子 内部引起裂痕，於固化體内部有產生缺陷之虞。因此，關於 含有0.5質量％以上游離CaO的製鋼熔渣，若事先予以熟化 (通常’蒸氣熟化等），使游離CaO水合成為Ca(〇H)2，則使 用作為骨材時不會發生體積變化，故為佳。若進行熟化至熔 渣的粉化率為2.5%以下左右為止即可。 此處’構成泥土固體粒子的礦物相’根據疏溲地區和發生 經歷而完全不同。因此，有時根據疏淡土的種類使得製鋼熔 渣所供給的Ca分過剩，有引起混練物之反應性不安定化和 100119512 201209013 接觸至硬化體之水的pH上升的案例。作為其對策’亦考慮 減少製鋼熔渣的配合量使Ca分的供給減少’但硬化體的重 量變輕，體積安定性亦降低。於此種情況中’在高爐溶渣微 粉末加上配合飛灰作為黏合材為佳。 . 飛灰係以非晶質的Si02，Al2〇3作為主體’故在發生過剩 . 鹼分的情況，可期待比結晶質材料迅速引起凝硬反應。但， 若過量配合飛灰，則黏合材中的Ca量過度變少，有損害疏 液土、製鋼熔渣、黏合材本來之反應安定性之虞。因此，配 合飛灰時，其配合量相對於高爐熔渣微粉末以30質量。/0以 下為佳。 因此’於使用高爐熔渣微粉末及鹼刺激劑作為黏合材之情 況’由上述同樣之理由而言，期望高爐熔渣微粉末與飛灰合 計含量為80〜95質量％，且殘餘部分係由普通波特蘭水泥、 石灰粉、消石灰、高爐水泥中選出1種以上所構成，且飛灰 相對於高爐熔渣微粉末以30質量％以下為佳。 如上述，本發明之人工石材，可大量使用疏浚土之同時， 亦可有效利用產業副產物的製鋼熔渣，且具有相當準硬石以 上之尚強度且具有比混凝土更輕量的性能，故非常有用於作 為设置於柔軟地基等之石材。 其次，說明關於本發明之人工石材的製造方法。 本發明之人工石材之製造方法中，配合泥土、黏合材及骨 材之製鋼m需要將添加水的混合#料混練，並使此混 100119512 13 201209013 練物水合硬化取得人工石材。 本發明係以有效利用疏浚土所代表之泥土為目的，故混合 材料中之泥土比例儘可能多者為佳，因此相對於混合材料中 之泥土、黏合材及粉粒狀之製鋼熔渣之泥土的比例（原來泥 土中所含之含有水分的比例）為4〇容積％以上為佳。另一方

when the steel is melted, it supplies helium ions and helium H ions. It is considered that the plasma is tempered by the two dredged soils to alleviate the reaction (IV), and high strength is obtained. Therefore, the mixture can be continuously used in a large amount by mixing and mixing the slag and the mixed material with the granules. Soil, hydrated hardened body with moderate specific gravity and high strength. The mass per unit volume of the artificial stone and the artificial stone is less than 2000kg/m3. JIS-A-5GG6. The specific gravity of the quasi-hard rock described in 1995. When applied to a soft foundation or the like, the stability of the artificial stone which is easily flowable by waves or the like is lowered. On the other hand, if the bitterness exceeds 22 〇〇kg/m ’, the average weight of the quasi-hard rock is applied to the case where it is desired to be used lightly, and there is no significant difference from the case of using ordinary stone. Also, it is difficult to ensure the full use of dredged soil. Therefore, the mass per unit volume is set to 2000 to 2200 kg/m3. Further, the strength of the artificial stone is equal to or more than the quasi-hard stone specified in JIS-A-5006:1995, that is, the uniaxial compression strength after aging on the 28th is 9.8 N/mm2 or more. Further, the natural stone is stable in strength, but in the case of the solidified body, variations occur depending on the blending conditions. Therefore, the uniaxial compressive strength after aging at 28 days is preferably 15 N/mm 2 or more. The soil to be used in the present invention is exemplified by dredged soil, and examples thereof include mud produced by excavation work, construction sludge, and the like. Here, the term "soil" refers to the general inability to accumulate and shows the flow that people cannot walk on. 100119512 9 201209013 Sex. As the approximate strength, the taper index specified in JIS A 1228: 2〇〇9 (the test method of the cone index of the hard soil) is 200 N/mm 2 or less. The soil represented by the soil is so thin that the more the mud is, the larger the ion (score) adsorption effect becomes, and it is difficult to obtain a suitable solidified body by the prior art, and thus the present invention is particularly useful. Specifically, the present invention is particularly useful in the case of soil containing coarse soil (sludge) having a particle diameter of 7 g or more and a particle diameter of 0.075 mm or less. As will be described later, the soil is used in a ratio of 40% by volume or more in the mixed material. Examples of the adhesive material include blast furnace slag fine powder, blast furnace slag fine powder to which an alkali stimulating agent is added, blast furnace cement, ordinary Portland cement, and the like. In addition, from the viewpoint of ensuring the strength of the solidified body and the production cost, it is desirable to add an alkali stimulating agent as a binder to the blast furnace slag fine powder from the viewpoint of reducing the environmental load as much as possible. By using the blast furnace slag micropowder and the irritant as a binder, it can be used as an alkali environment to exhibit the hydraulic properties of the blast furnace slag micropowder. That is, the hydration reaction of the blast furnace slag fine powder can be promoted to ensure the strength of the solidified body. Further, in the case where the ordinary Portland cement is used as the adhesive, the pH of the solidified body when it is immersed in water is increased, which is greater than the case of using the blast furnace slag fine powder and the alkali stimulating agent. Therefore, in consideration of the load on the surrounding environment, it is suitable to use the blast furnace scum fine powder and the stimulating agent. As the stimulating agent, for example, lime powder, hydrated lime, ordinary batter 100119512 10 201209013 blue cement, kiln cement, or the like can be used. In this case, it is preferred that the blast furnace slag fine powder is contained in an amount of 80 to 95% by mass and the residual portion is one or more selected from the group consisting of lime powder, hydrated lime, ordinary Portland cement, and blast furnace cement. When the blast furnace slag micropowder and the irritant are used as the binder, if the proportion of the blast furnace slag fine powder is 80% by mass or more, the remaining alkali component does not remain in the solidified body. Therefore, when a solidified body is used in the sea, the load of the alkali on the seawater environment is small. Moreover, it is also economically beneficial. On the other hand, even if the proportion of the blast furnace slag fine powder exceeds 95% by mass, it can be kneaded and cured. However, if it is 95% by mass or less, the effect of the stimulating agent can be easily reduced due to the ease of dispersion and the effect of the dredging soil suppression effect. Therefore, the effect of adding the blast furnace smeared powder is high, and it is not necessary to use various raw materials, and it does not become a device. The burden is therefore economically appropriate. There is no particular limitation on the type of steel to be inspected for the month of the month, and the molten iron pretreatment marrying (de-slag, de-slag, desulfurization (four), etc.), converter decarburization slag, electric furnace melting material' may be used. One or more types are required. The steelmaking money is preferably a particle size having a maximum particle diameter of 25 mm or less. It is also possible to use a particle size larger than this. However, the 'preparation _' contains free CaQ, and it is stabilized by steam curing, etc., and the slag granules are large and free of internal remnants (five): the energy becomes high 曰 'expands during long-term use and becomes defective The possibility of the cause is reduced by the effect of St. 2 as the aggregate, that is, the volume stability and the proportion of the particles of 80" HG 15_ or more are more than 80% by mass of the entire steel melting. There is no particular limitation. However, the degree of inspection (Ming 2) 100119512 201209013 is better if the effect of the strength is greater. However, if it is too high, the residual amount of free CaO tends to increase as described later. In addition, in the case of excessive alkalinity, there is no basic problem in the stabilization treatment of the steel slag in advance, such as steam curing. However, the aging treatment tends to become powdery, so it is difficult to ensure the function as a bone. The particle size of the material acts, and the intrinsic amount of free CaO also increases, so the maturation time must be longer than usual, and sometimes the residual CaO remains inside and the deviation of volume stability becomes large. Therefore, alkalinity (Ca〇/Si) 〇 2) is 2.0 In the case where the slag produced by the steelmaking step contains 5% by mass or more of free CaO, the steel slag is aged to a pulverization rate of 2.5% or less, and is used as the material (aggregate) of the present invention. It is better. Regarding the higher slag, the free CaO remains much. The free CaO quickly becomes ca(OH)2 by contact with water, which has the advantage of being easily ionized and participating in the reaction. However, on the other hand, in the slag The free CaO remaining in the particles swells when it comes into contact with the water that has penetrated, causing cracks inside the particles, and causing defects in the solidified body. Therefore, the steel slag containing 0.5% by mass or more of free CaO is aged beforehand. (In general, 'steam curing, etc.') When the free CaO water is synthesized into Ca(〇H)2, it is preferred that the volume change does not occur when used as an aggregate. If the aging is performed until the slag has a pulverization rate of 2.5% or less. It can be left and right. Here, the 'mineral phase constituting the solid particles of the earth' is completely different depending on the dredging area and the experience of occurrence. Therefore, the Ca supplied by the steel slag is sometimes divided according to the type of the thin soil. There is a case in which the reactivity of the kneaded material is unstable and the pH of the water in contact with the hardened body is increased by 100119512 201209013. As a countermeasure, it is also considered to reduce the amount of the molten steel slag to reduce the supply of Ca, but the hardened body The weight is lighter and the volume stability is also reduced. In this case, it is better to use the slag slag micropowder plus fly ash as the binder. The fly ash is based on amorphous SiO 2 and Al 2 〇 3 as the main body. Therefore, in the case of excessive alkalinity, it is expected to cause a hardening reaction faster than the crystalline material. However, if the fly ash is excessively blended, the amount of Ca in the binder is excessively small, and the lyophobic soil and the steel slag are damaged. The original reaction of the adhesive material is stable. Therefore, when the fly ash is blended, the blending amount is 30 mass with respect to the blast furnace slag fine powder. /0 is better. Therefore, in the case of using the blast furnace slag fine powder and the alkali stimulating agent as the binder, for the same reason as described above, it is desirable that the total content of the blast furnace slag fine powder and the fly ash is 80 to 95% by mass, and the residual portion is One or more of Portland cement, lime powder, slaked lime, and blast furnace cement are selected, and the fly ash is preferably 30% by mass or less based on the blast furnace slag fine powder. As described above, the artificial stone of the present invention can use the sparse soil in a large amount, and can also effectively utilize the steel slag of the industrial by-product, and has a relatively strong strength above the quasi-hard stone and has a lighter weight than the concrete, so It is very useful as a stone set on a soft foundation. Next, a method of manufacturing the artificial stone of the present invention will be described. In the manufacturing method of the artificial stone of the present invention, the steel m mixed with the soil, the binder and the bone material needs to be mixed with the water-added material, and the artificial stone is obtained by hydrating and hardening the mixture. The present invention is for the purpose of effectively utilizing the soil represented by the dredged soil, so that the proportion of the soil in the mixed material is as good as possible, and therefore the soil relative to the soil, the binder and the granular steel slag in the mixed material The ratio (the ratio of the moisture contained in the original soil) is preferably 4% by volume or more. On the other hand, if the ratio of the soil is 60% by volume or less, the mass per unit volume is easily made 2000kg/m or more, and since the ratio of the aggregate must be low, the solidified body does not become brittle. Durability. Therefore, the ratio of the soil to the soil, the binder, and the powdery slag in the mixed material is preferably 40 to 60% by volume. Moreover, in a better manufacturing condition, the soil slag containing soil, binder and powder granules having a water content of 180 to 250% is contained, and the ratio of soil to soil, binder and powder slag is The blending amount of 40 to 60% by volume and the steel slag is mixed with a mixed material of 750 kg/m 3 or more per volume of the mixed material, and the kneaded product is hydrated and hardened. Here, the water content ratio of the so-called dredged soil is determined by the water content of the dredged soil as A (% by mass) and the solid content is defined as B (% by mass), and the water content ratio = (A/B) xl Out. According to such a preferable manufacturing condition, it is possible to stably produce a hydrated hardened body having a mass per unit volume of 2000 to 2200 kg/m 3 and a uniaxial compressive strength of 28 N or more after aging, and having a small variation in characteristics. . The proportion of dredged soil is the volume ° /. The mixing amount of the steel slag is 1000kg/m3, and the mixture is hydrated and hardened to obtain the solid 100119512 14 201209013. When using the different soil water content, the slump and the solidified body of the mixed material are investigated. Characteristics. The results are shown in Table 1. Further, the strength of the cured body was measured by the same method as in Example, and the uniaxial compressive strength after 28 aging was measured. According to Table 1, if the water content of the dredged soil is less than 180%, the characteristics of the solidified body are sufficient, but since there is no fluidity (no discrimination) in the mixed material, industrial production is difficult, even if it can be manufactured. Also, the characteristic deviation becomes large. On the other hand, when the water content ratio of the sloping soil is 240%, the strength starts to decrease, and at 260%, the strength is greatly lowered. Therefore, the water content ratio of the dredged soil is expected to be 180 to 250%, and more desirably 240% or less. [Table 1] Moisture ratio of soil (%) Slipping degree of mixed material (cm) Characteristic strength of solidified body (N/mm2) Mass per unit volume (kg/m3) 160 X 16.1 2150 180 3.0 17.4 2136 200 3.5 18.4 2124 220 4.0 19.2 2114 240 4.2 16.0 2105 260 4.8 12.8 2098 Further, the steel slag must be mixed in the viewpoint of the effect of supplying the Ca ions and OH ions as described above, and also ensuring the volume stability of the solidified body. The amount of the material is more than 750 kg/m3 or more, and more preferably 1000 kg/m3 or more. However, if the blending amount of the steel slag is 1450 kg/m3 or less, the mass per unit volume of the solidified body is not excessive, and it is not necessary to use a large amount of water to make it lightweight, and sufficient strength can be obtained, so that the steel and slag are blended. The amount is preferably 1450 kg/m3 or less. 100119512 15 201209013 Soil such as dredged soil, if necessary, remove foreign matter by sieve or the like. As a kneading means for the mixed material, for example, it is also possible to use a kneading device for the new concrete of the shovel, but it is also possible to use a heavy machine for civil engineering such as a shovel and to perform it in a courtyard such as a house. In order to cure the kneaded material, for example, it flows into a suitable frame and is solidified and cured (hydrated and hardened), and may be layered and solidified (hydrated and hardened) in a courtyard such as an outdoor house. In particular, in the case of mass production of stone, it is preferable to set it in a layer in the courtyard. During curing and aging, it is generally about 7 为止 until the target compressive strength is obtained. The obtained stone 'is broken into an appropriate size as needed. This crushing treatment can also be carried out using a crusher. Further, if the kneaded material is placed in a layer in the courtyard as described above, the solidified body of the garden is roughly crushed by a crusher, and secondly, it can be crushed by a crusher. Further, usually, the solidified body (block) of the crushing treatment is sieved to obtain a block having a predetermined size. For example, in the case of using a latent coffin or the like, a block having a size of about 150 to 500 mm is obtained. The dredged soil that occurs in the dredging project, the water content is biased according to the dredging site. In the case of the cultivation of aquatic products (seaweed, oyster filling, etc.) in the vicinity of the dredging project, the contamination of the seawater caused by the dredging project has a β product. Therefore, dredging works should not be carried out throughout the year, and the engineering period is limited (seasonal). When the present invention is practiced in such a situation, the lyophobic soil produced by the dredging works is stored in the dredged soil storage field, and it is preferable to use the dredged soil to reduce the amount of the phased body. The county has the following effects. W Even if the water content of the sparse soil is different from that according to the dredging site, etc., the moisture content of the dredged soil can be made uniform by depositing the sludge in the m field. (ii) There are restrictions on the construction period of dredging. Even if it is impossible to collect the dredged soil during the year, it can be stabilized and supplied to the solidified soil through the storage of mud in the dredged soil. (111) The evaluation, management, and adjustment of the water content ratio can be easily performed by storing the dredged soil in the dredged soil storage site. FIG. 3 shows an embodiment of the present invention using the dredged soil placement field, and the dredging project occurs. Dredged soil, stored in the dredged soil. The form and structure of the dredged soil placement field are arbitrary. For example, an earthen embankment in which sand and slag are deposited in the courtyard is formed, and the dredged soil can be stored on the inner side. The dredged soil that occurred in the dredging project, regardless of its water content ratio and other traits, was moved into the dredged soil storage site and muddy. The dredged soil placement field is appropriately supplied in a clay type during the production of the solidified body (artificial stone), and a lightweight artificial stone can be obtained according to the above-described manufacturing method. [Examples] The materials were blended under the conditions shown in Tables 2 and 3 and kneaded (mixed for 5 minutes in a 0.75 m3 kneading apparatus and discharged after a specified period of time), and the kneaded material of the mixed material was in a diameter l〇 〇mmx height 200mm size model 100119512 17 201209013 Formed and deuterated, the production of solidified body (artificial stone) n used in the Setouchi sea bottom collection (four) is divided into 90% by volume, if necessary, add water for moisture adjustment. Further, as the steel material for the aggregate (four), the steam aging is performed in the converter slag containing 35 mass% of free CaO so that the powdering rate is I 』% (particle diameter 0-25 mm; particle diameter 〇.i5 mm or more is 80) Quality #〇/,,; L, Bei Dong/〇M), using steel with different apparent density to refine the fishing A and steel-making Hyun: Pan only Gently. The uniaxial compression strength of the cured body after day ripening was measured by a compression test (JIS-A-1108: ·6). The results are shown in Table 2 and Table together with the mass per unit volume of the solidified body, etc. According to Table 2 and Table 3, the cured body of the present invention has a high strength of an appropriate unit volume mass (2000 to 2200 kg/m3). . In contrast, the cured body of the comparative example of Ν〇1〇~14 and Νο.33 is due to the low water content of the dredged soil, the excessive use of the steel slag, the excessive proportion of the loose soil, and the unused steel slag.
