Operating expenses were also required, leading to an increase in costs. Furthermore, light + M
In order to obtain a W product, a foaming agent was mixed in to form a large number of bubbles inside. This blowing agent is produced by a chemical reaction.

の製造が簡単ではないという問題があった。Since it is a mechanism that generates gas, the temperature of the raw material, air temperature, etc. affect the amount and shape of foaming, so detailed control is required. Therefore, it requires the skill of the operator and is not easy to manufacture. There was a problem.

大量に発生する石炭灰の処理が大きな問題となることか

Since the treatment of coal ash generated in large quantities is a major problem, it is important to develop technology for its effective use.
本発明は、上記事情に鑑みなされたもので、石炭灰の有

。The present invention was made in view of the above circumstances, and aims to provide a lightweight building material that can effectively utilize coal ash and does not require crushing equipment for the main material, such as silica stone, or a blowing agent. .
〔問題点を解決するための手段・作用〕本発明は、軽量

By molding into a predetermined shape and curing the molded product.

に利用したものである。By utilizing the lightness of coal ash without mixing a blowing agent, we aim to reduce the weight, and since coal ash is originally spherical fine particles, there is no need for crushing equipment, making effective use of coal ash. This is what I did.

が、目的とする製品に対応して軽量化の程度も異なるた
め、この石炭灰自体の混入を適宜行なってもよい。First, coal ash granulated sand is made by adding cement and water to coal ash and mixing and granulating it at high speed. Its size should be less than 5m in diameter. Coal ash contains approximately 60% silicon dioxide as a component and is glassy and approximately spherical in shape. Although the true specific gravity is 2.0 to 2.2, the bulk specific gravity is 0.8 to 1.0 because the content is white and has voids. When this is granulated as described above, new voids are formed between the coal ash particles, so the bulk specific gravity of the coal ash granulated sand is 0.5.
~0.7. A feature of the present invention is that the main material is coal ash granulated sand that has many voids and has a small bulk specific gravity. This coal ash granulated sand is mixed with a binder such as cement and water, and then formed into the shape of, for example, a concrete plate. Thereafter, this molded product is cured by steam curing, autoclave curing, or the like. Incidentally, coal ash itself may be further mixed in an appropriate amount. In this case, the degree of weight reduction will be somewhat reduced because the only voids will be those of the coal ash itself, but the weight will be reduced depending on the desired product. Since the degree of carbonization differs, the coal ash itself may be mixed in as appropriate.

〔発明の効果〕
本発明によれば、軽量建材を石炭灰とセメント及び水の
混合物から造粒して形成した石炭灰造粒砂を主材として
、結合剤及び水を混入して所定形状に成形し、その成形
物を養生して形成したので。1. Steam curing [Effects of the invention] According to the present invention, a lightweight building material is mainly made of coal ash granulated sand, which is formed by granulating a mixture of coal ash, cement, and water, and a binder and water are mixed therein. It was formed by molding it into a predetermined shape and curing the molded product.
石炭灰の有効利用を図ることができる。軽量化のために
石炭灰自体の軽量性を利用しているため、従来のような
発泡剤が不要となり、低コスト化を図れる。更に石炭灰
はもともと球形の微粒子であるため、粉砕工程が不要と
なり、従来のような粉砕設備が不要となるためその分、
スペースの節減及び低コスト化を図ることができる。Coal ash can be used effectively. Since the lightweight nature of coal ash itself is used to reduce weight, there is no need for a conventional foaming agent, resulting in lower costs. Furthermore, since coal ash is originally spherical fine particles, there is no need for a pulverization process, and conventional pulverization equipment is not required.
It is possible to save space and reduce costs.
