生せしめた後に、セメントノロ又はセメントモルタル等
と混合して、型枠に打設し硬化せしめる方法であった。Conventional methods include sifting aggregates such as gravel, selecting those with a uniform particle size, mixing them with cement slag or cement mortar, pouring them into molds, and letting them harden; or using powders such as fly ash. This is a method in which a granulated material such as coal ash is granulated to an approximately constant particle size by adding a binder such as cement, and is then hardened and cured, mixed with cement slag or cement mortar, etc., and poured into a formwork and allowed to harden. Ta.
しかしながら、従来の方法で製造したものは、透水係数
が小さいという問題点があり、歩道板などに使用したと
き、水はけが悪いという欠点があった。However, those produced by conventional methods have a problem of low water permeability, and when used for sidewalk boards, etc., they have the disadvantage of poor drainage.
加えて、石炭灰等の造粒物を硬化養生して骨材とした後
者のものは、骨材製造工程において硬化及び養生工程を
要するという問題点があり、一定の期間と設備が必要で
あった。In addition, the latter method, which is made by hardening and curing granules such as coal ash, has the problem of requiring hardening and curing processes in the aggregate manufacturing process, and requires a certain period of time and equipment. Ta.
また、砂利等を骨材とした前者の方法によるものは、重
いという問題点があり、運搬使用等に不都合であった。Furthermore, the former method using gravel or the like as aggregate had the problem of being heavy, making it inconvenient for transportation.
この発明の目的は、上記問題点を解消するためになされ
たもので、簡略化された工程によって、軽量で透水効果
の大きい透水硬化体の製造方法を提供することである。An object of the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method for manufacturing a water-permeable cured body that is lightweight and has a large water-permeable effect using a simplified process.
上記の目的を達成するために、本発明に係る透水硬化体
の製造方法は、フライアッシュ又はスラグ、等の粉体、
又はこれらの混合物に、結合材を加えて造粒し、その直
後に型枠につめて硬化せしめることを特徴とするもので
ある。In order to achieve the above object, the method for producing a water-permeable hardened body according to the present invention uses powder such as fly ash or slag,
Alternatively, the mixture is characterized by adding a binder to the mixture, granulating it, and immediately thereafter filling it in a mold and hardening it.
以下、本発明の詳細な説明する。下記第１表に示すＡ及
びＢ配合によって具体的に試験体を製造した。The present invention will be explained in detail below. Test specimens were specifically manufactured using the A and B formulations shown in Table 1 below.
第 １ 表
上記配合の各々について、造粒機の回転数のみを変えて

造粒物を、それぞれ、硬化養生せずにそのまま直径１０
ａＩＩ・高さ２０ａｌの円筒型枠に振動を加えながら打
設した後、硬化養生して試験体を製造した。Table 1 For each of the above formulations, three types of granules with particle sizes of 2 to 3 mφ, 3 to 4 mφ, and 4 to 5 mmφ were prepared without hardening and curing by changing only the rotation speed of the granulator. Diameter 10 as it is
After pouring into a cylindrical formwork with a II height of 20 al while applying vibration, the test specimen was hardened and cured.
これらの試験体について、ＪＩＳＡ１２１８（土の透水
試験方法）に準じて試験を行い下記第２表の結果を得た
。These specimens were tested in accordance with JISA1218 (soil permeability test method), and the results shown in Table 2 below were obtained.
第 ２ 表
この結果を下記第３表に示す土の透水性と比較しても１
本発明による試験体が礫に匹敵する高い透水性能を有す
ることが明らかである。Table 2 Comparing this result with the soil permeability shown in Table 3 below, the result is 1.
It is clear that the specimen according to the invention has a high water permeability comparable to gravel.
第 ３ 表
〔発明の効果〕
上述のとおり本発明によれば、石炭灰を有効に利用して
、透水係数の大きい軽量な透水硬化体を。Table 3 [Effects of the Invention] As described above, according to the present invention, coal ash is effectively utilized to produce a lightweight water-permeable hardened body with a high coefficient of water permeability.
石炭灰から１工程で製造することができる。It can be produced in one step from coal ash.
更に、本発明によって製造された透水硬化体は。Furthermore, the water-permeable hardened body produced by the present invention is as follows.
雨水を土中に浸みこませる歩道板等の建設資材−下水を
濾過して土中に浸みこませる排水桝等の給排水濾過材、
その他園芸植物囲いなどその用途は極めて広い。Construction materials such as sidewalk boards that allow rainwater to seep into the soil - Water supply and drainage filtration materials such as drainage basins that filter sewage and allow it to seep into the soil;
It has a wide range of uses, including enclosures for other garden plants.
