Description

Cement Inorganic Ground Injection Material Composition and Method of Use {CEMENT BASE GROUTING MATERIAL AND CONSTRUCTING METHOD USING THE SAME}

The present invention relates to the injection material of boring grouting construction for the order and ground reinforcement of buildings or civil structures, and more specifically, to large-scale construction such as subway, tunnel, road construction, as well as construction sites of apartments, buildings, etc. It is a fast-hardening cement mineral ground injection material used for ground boring grouting work to reinforce ground and block leachate in most construction works. Time for the injection material to lose fluidity to form a gel-like structure), high initial and long-term strength, etc., as well as eco-friendly cement-inorganic ground injection material that does not cause permanent durability and environmental pollution due to no dissolution. The composition relates to.

The technology of ground injection material was developed mainly in developed countries such as Japan, Europe, and the United States, along with the construction technology. The solution type (wet liquid system) and suspension type were developed.In Korea, LW method and SGR method were introduced from Japan, and silicic acid called cement and water glass Suspension type ground injection materials employing soda are now commonly used. Suspension type ground injection material using soda silicate is commonly used because it is easy to penetrate into the soil as a liquid form of silicate, which is easy to realize fast gel time characteristics, and the material is relatively economical. since the high ionization characteristics leached and then developed with due gel formation of silicic acid soda Na ⁺ component in to proceed, and the strength is reduced, the long term, also collapsed the tissue loses its characteristics of order and ground reinforcement as well as the problem of the severe groundwater contamination Generates.

For this reason, in recent years, the SGR method using special silicate fasteners and high-powder cement, which significantly reduced the content of Na ⁺ , which is a leaching material of sodium silicate, has been developed and put into practical use. The method of using special silicate quickeners greatly reduces soluble materials and significantly improves the problems of tissue breakdown and environmental pollution due to leaching, compared to the conventional method of using sodium silicate, but the gel time due to early reaction Since Na ⁺ was not completely removed in order to obtain a long-term leaching problem, the long-term strength expression is insufficient compared to cement mineral-based fillers, and the reinforcing properties are not excellent. In addition, there is a problem that the material cost increases compared to the ground injection material using sodium silicate. Cement Inorganic ground injection material is the latest technology commercialized with the development of CSA (Calcium Sulpho Aluminate) cement for quick quenching in Japan. It is not environmentally stable due to almost no leaching, and it has excellent long-term strength characteristics. And because the reinforcing properties are permanently maintained, they exhibit the most excellent properties compared to other conventional ground injection materials. In Korea, as environmental pollution has become a sharp issue at construction sites, some companies have adopted Japanese technology and quenching cement and applied it to cement-based mineral fillers, but the Japanese imported CSA-based cement for fastening is very expensive. As such, there is no universal commercialization of the ground injection material manufactured using the same.

Ground injection materials used in boring grouting are usually commercialized in two types, E type and N type. In general, gel time is about 10 seconds in case of fastening type. Gel time is expressed in about a second. In addition, the fastening type and the finishing type are respectively composed of two powder compositions, which are mixed separately with water in a mixer, put into the ground by equipment, and then combined with each other at the construction site to react. Boring grouting works are usually constructed in such a way that the ground type injection material is first constructed and the groundwater is blocked to block groundwater, and then the complete type land injection material is constructed and widely penetrated into the soil to reinforce the ground. It is constructed continuously at. Type A powder composition consists of two types of fast-acting CSA mixtures and additives, and the type B powder composition is composed of a high-powder cement mixture. The material is applied. At this time, the gel time control of fastening and completion is controlled by varying the amount of ground injection material, the amount of mixing, and the amount of additives for controlling gel time, and the minimum number of mixers required for one equipment for mixing the ground injection material in the boring grouting work A total of four are required, two for two ground filler mixtures and two for a complete ground filler mixture. This is because the boring grouting equipment for silicic acid-based injection material, which is the current universal construction equipment, has three mixers. Therefore, when the cement mineral-based injection material is applied, it is cumbersome to change the equipment. It is another obstacle to commercialization.

The present invention, while satisfying the characteristics of the injection and gel time of the existing ground injection material, while developing a cement inorganic ground injection material excellent in environmental friendliness, high-strength expression characteristics and durability of the early and long-term age, the existing Japanese imported rapid CSA system Unlike the ground injection material using cement, the ground injection material using general CSA cement that has not been commercialized as a ground injection material is developed, and expresses more than the same characteristics as the ground injection material using the fast-acting CSA cement. By providing the same groundbreaking price competitiveness, it is possible to provide a composition of ground injection material that can realize universal commercialization, and to apply the same amount of powder mixture and mixed quantity used in the fastened and final ground injection material. Existing silicic acid by reducing the number of mixers to the same three as the existing silicic acid-based filler The technical problem is to provide a mixing process that can be applied to the system as it is.

In order to achieve the above technical problem, the cement inorganic ground injection composition of the present invention comprises (a) 85 to 99 wt% of general CSA cement having a powder degree of 6,000 to 9,000 cm 2 / g based on the weight of the powder, potassium, sodium, calcium A first composition comprising 1 to 15% by weight of one or more accelerators selected from the group consisting of chloride salts, carbonates, sulfates, acetates, silicates and oxalates containing aluminum-based metal ions,

The accelerator content of the second composition in the composition of the present invention may be 5% by weight or more based on the weight of the powder of the second composition. Alternatively, the accelerator content of the second composition may be less than 5% by weight. As such, the ground injection material composition of the present invention is composed of the first and second compositions, and by controlling the content of the promoter included in any one of the compositions, it can be used as a fastener or a complete agent.

In another aspect, the present invention provides a method for producing a slurry comprising: (c) providing a first mixed slurry comprising a second accelerator for promoting a reaction of a general CSA cement and a portland cement in a second mixer to the first mixer; (d) providing a second mixer slurry to the second mixer comprising portland cement, anhydrous or hemihydrate gypsum, and a first promoter for catalyzing the reaction of the general CSA based cement in the first mixer; And (e) injecting the first mixed slurry of the first mixer and the second mixed slurry of the second mixer into the ground and reacting the ground injection material.

The method of the present invention comprises: (f) a third mixing slurry comprising a third mixer comprising a second promoter to facilitate the reaction of Portland cement, anhydrous gypsum or hemihydrate gypsum, and the Portland cement in the first mixer; The method may further include providing a mixed slurry, wherein the content of the second promoter in the third slurry may be lower than the content of the second promoter in the second slurry.

Thus, by using the third slurry, the ground injection material construction method of the present invention, after the step (e), (g) the first mixed slurry of the first mixer and the third mixed slurry of the third mixer Further comprising the step of adding the reaction to the ground, it is possible to implement the fastening and completion process during the ground injection using three mixers.

In the method of the present invention, the first promoter may be one or more promoters selected from the group consisting of carbonates and oxalates including lithium and calcium metal ions, and the second promoters are chloride salts, carbonate salts, sulfate salts, acetate salts, silicates And one or more promoters selected from the group consisting of oxalates.

Hereinafter, the present invention will be described in detail by explaining preferred embodiments of the present invention.

Construction of the ground injecting material is usually carried out by constructing the ground-type ground injecting material and then constructing the finished ground injecting material. First, the quick-type ground-filled material performs an order function that prevents water generated in the ground hole in an instant, and the finished ground-filled material performs a reinforcing function.

In the present invention, the first composition is composed of general CSA-based cement and additives, and the second composition is composed of high powder cement and other mixtures. These compositions may be powder compositions, and may be present in the form of a slurry by adding water thereto.

Hereinafter, each component which comprises the cement inorganic ground-based injection material composition of this invention is demonstrated in detail.

(1) Type A powder composition

a. General CSA Cement

CSA cement is usually used together with Portland cement to make fast cement products, which react with Ca ²⁺ ions liberated in Portland cement and CSA cement to ethrinite (3CaO · Al ₂ O ₃ · 3CaSO ₄ 32H ₂ O) to form a needle-like fast-moving material. As shown in the chemical composition table shown in [Table 2], the general CSA used in the present invention is known as a material having low reaction activity because there is a difference in composition from the quenched CSA cement and also in the firing process. Fastened CSA cements exhibit hardening properties ranging from a few seconds to several minutes, and are used for fasteners such as liner materials, whereas general CSA cements typically exhibit hardening properties of tens of minutes to hours. The same applies to fast-hardening products. Therefore, it is known that it is very difficult to apply general CSA-based cement to a product that needs gel time in a few seconds, such as ground injection material, and the price difference is 2 to 4 times. Therefore, in order to improve the reaction characteristics, the powder with the specific surface area more than twice that of general cement was also manufactured with high powder of 6,000 ~ 9,000 ㎠ / g. While the ground injection material using the fastened CSA cement was used the retardant to secure the pot life, In the present invention, the reaction properties were enhanced by adding an accelerator capable of acting as a Ca ²⁺ ion to promote the reaction of the general CSA cement in the A powder composition in the B powder composition.

b. accelerant

If the accelerator added in the A-type powder composition has a small effect on the reactivity of the CSA, and an admixture capable of promoting the reaction of the high-powder portland cement in the B-type powder composition is added, and the A-type powder composition is mixed with water, While ensuring sufficient pot life, it was possible to promote the reaction when contacted with type B sludge. In general, the reaction of Portland cement is known to be accelerated by the increase of alkali metal or alkaline earth metal ions such as potassium, calcium and sodium. Therefore, chloride, carbonic acid, sulfuric acid, acetic acid, silicic acid, and hydroxyl-based metal salt accelerators capable of supplying these metal ions were added in a range of 1 to 15% based on the total weight of the A-type powder composition.

(2) Type B powder composition

a. Portland Cement & High Powder Portland Cement

Portland cement in the present invention is not only to supply calcium ions that can accelerate the initial reaction of the CSA-based cement, it is an important component for improving the long-term strength and durability of the ground injection material. Considering the reaction rate and the penetration into the soil, the higher the powder, the better, but general Portland cement is also possible depending on the condition of the ground and economics. The cement used is preferably 50 to 80% by weight of the type B powder composition.

b. Kilndust

Kiln dust is a dust collecting dust of Pusan dust generated when firing clinker in cement factory. Since the powder is extremely fine cement component of around 10,000 ㎠ / g, the injection property is excellent, and the SO ₃ content is high, so the long-term strength property is high. outstanding. However, since the chlorine content can cause corrosion of the rebar, it is not possible to use it as an existing cement and is being treated as waste. In the case of ground injection material, since there is no reinforcing bar, it is easy to use the above characteristics and contributes to the cost reduction of material costs in terms of waste recycling. It is preferable that the amount is 0 to 30% based on the weight of the B-type powder composition, but when excessively applied, the CaO content is low, making it difficult to express gel time.

c. Anhydrous or semi-hydrated gypsum

Gypsum is a material that secures working time by delaying the condensation of portland cement. It is used in cement production, and it is also used as a material to enhance strength by forming erythrite using together with portland cement and CSA cement. In the present invention, the amount used is preferably 10 to 50% with respect to the weight of the B-type powder composition, but below this, the strength expression of the ground injection material is insufficient, and when it is excessively added beyond this range, it is difficult to secure gel time. have. Semi-hydrated gypsum is superior to anhydrous gypsum in terms of securing gel time due to its excellent hydraulic properties, but has a disadvantage of being expensive.

d. accelerant

The accelerator added in the powder composition of B is one or two carbonates and oxalic accelerators containing lithium and calcium metal ions to promote the reaction of the general CSA cement in the A powder composition and the Portland cement in the B powder composition. Use at least 1% to 10% by weight of the type B powder composition.

e. Dispersant

Since the weight% of the B-type powder composition in the slurry mixed with water is higher than the weight% of the A-type powder composition in the slurry mixed with water, the fluidity is relatively low, the viscosity is relatively high, and aggregation occurs over time. Severe. Dispersing agents can improve the above problems to prevent the aggregation of particles, increase the fluidity at a low water cement ratio can obtain the effect of securing workability and strength. The dispersant according to the present invention uses one or two or more of naphthalene sulfonate, melamine sulfonate, and polycarboxylic acid-based water reducing agent in an amount of 0.5 to 2.0% based on the weight of the B-type powder composition.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.

Examples 1-4

Each of the A type slurry and the B type slurry having the compositions listed in Table 3 below was prepared. Here, in Example 1, the accelerator was not added to the A slurry, but the accelerator (5% of the total weight of the B powder was 10% by weight) was added only to the slurry of the B slurry. This is the case where an accelerator (5% relative to the total weight of the A-type powder) is added to the B-type slurry without adding the accelerator to the slurry. In the case of Example 3, accelerators (5% to 100% of the total weight of type A powder and 2.5% to the total weight of the type B powder) were added to both the type A slurry and the type B slurry, respectively. In the case where the accelerator content is reduced, Example 4 shows the accelerator (5% for 100% of the total weight of type A powder and 5% for the total weight of the type B powder of 100.5%) in both type A slurry and type B slurry. Is added, but the promoter content of the type B slurry is increased compared to Example 3.

Gel time, compressive strength (kgf / cm 2), viscosity of Form B slurry, Na 2 O content, and powder level were measured using the prepared A and B slurry.

Gel time was measured in two paper cups each containing the A type slurry and B type slurry, mixed them in one cup, and then alternately transferring the two paper cups to the other paper cups until it solidified.

The compressive strength was measured according to the standard of KSL 5105, and the viscosity of the B slurry was measured with a B viscometer. The Na 2 O content was measured by chemical analysis of the sample which solidified after mixing and settled.

Measurement results of Examples 1 and 4 are shown in Table 3 below.

Examples 5 and 6

Example 5 is for the case of replacing the kiln dust with cement in the type B slurry compared to Example 4, Example 6 is to increase the content of the kiln dust contained in the type B sludge compared to Example 4 Example. As described above, the gel times, compressive strengths (kgf / cm 2), type B slurry viscosity, Na 2 O content, and powder levels were measured as described above.

Example 7, 8

Example 7 is an example of the case where the content of the gypsum is increased or decreased while the content of the kiln dust in the type B slurry is the same as compared with Example 4. Each experimental result is shown in Table 3 below.

Example 9

Compared with Example 4, in Example 9, no dispersant was added to the B slurry. The experimental results are shown in Table 3 below.

* Does not measure compressive strength because gel time is too long

As can be seen from the experimental results of Examples 1 to 4, when the accelerator was added to only one slurry (Examples 1 and 2), the gel time was lower than when both were added (Examples 3 and 4). It can be seen that it is very long, and the gel time is shortened when the content of the accelerator is large (Example 4> Example 3).

As can be seen from the comparison of Examples 4, 5 and 6, gel time was found in Example 4 when no kiln dust was added (Example 5) and when a large amount of kiln dust was added (Example 6). It can be seen that the longer than. In other words, it can be seen that the appropriate amount of kiln dust should be added to reduce the gel time given the content of the accelerator. This is also true for the compressive strength.

As can be seen from the comparison of Examples 4, 7, and 8, the gel time increases and the compressive strength decreases in the case of Example 7 having a lower gypsum content and Example 8 having a higher gypsum content than Example 4. It can be seen that it is accompanied. Therefore, it can be seen that the gypsum content should be in an appropriate range in order to design the injection material having good gel time and compressive strength when the content of the accelerator is fixed.

In addition, as can be seen from the comparison of Examples 4 and 9, it can be seen that addition of the dispersant affects the gel time and the compressive strength.

On the other hand, in Examples 1 to 9 of the present invention about 0.7% by weight of Na 2 O based on the total solids content was detected, it can be seen that this is a very low value compared to that of Comparative Examples 1 to 3.

Embodiments of the present invention described above are presented to evaluate the effect of each composition added in the present invention. For example, while in Example 4 Example 4 is useful as a fastener in terms of gel time and compressive strength, and Example 9 is useful as a finisher in terms of gel time and compressive strength, It is significant within the scope of the accelerator, and it is apparent that if the content of the accelerator is increased, the gel time characteristics will be improved even if the kiln dust content is reduced as in Example 4. This also applies to other additives in the present invention.

According to the present invention, there is provided an inorganic ground injection material composition which can use the existing equipment for injection of the ground injection material, that is, the number of mixers as it is. The ground injection material composition of the present invention can provide a ground injection material having high strength while satisfying the gel time characteristics of the conventional inorganic injection material.

In addition, the ground injection material of the present invention is environmentally friendly because there is no fear of soil contamination because the Na 2 O content contained in the injection material is very low compared to the conventional ground injection material.

In addition, the ground injection material of the present invention by using the conventional silicic acid-based ground injection equipment as it is to perform the injection operation of the quenching and completion agent with conventional equipment can be applied as it is conventional construction method.
