のである。In this case, it is common to use foundry sand such as silica powder as the aggregate for cement slurry for manufacturing sheet-like cement building materials such as asbestos cement boards, and for manufacturing thick cement building materials such as mortar molded products. River sand, crushed stone, etc. are generally used as aggregates for mortar forming materials. However, these aggregates did not have sufficient adhesion to cement hydrate, and there was a problem in that they could not exhibit the sufficient strength of the cement 1% JR material. Also, these are 1 piece, 1 piece of print.
However, in this case, the strength of the cement-based building materials further decreases, cracks occur, and other quality problems occur. Problems also arise above.

Thick cement-based building materials are manufactured by mixing cement, aggregate, etc. with water to prepare a paste-like mortar forming material, which is then molded by press molding or the like and cured. In this case, recrystallized silica component powder is used as at least a part of the aggregate in cement slurry or mortar forming material.

ック発生などの問題がないものである。As the recrystallized silica component powder, pulverized waste materials of siliceous ceramic products such as tiles and porcelain, or powders or pulverized materials of thermally modified silica stone, such as quartz schist, can be used. These recrystallized silica component powders have a serrated surface, have good ffi adhesion to cement hydrate, and have high hardness, so they can fully function as an aggregate. , which can increase the strength of cement-based building material products. Furthermore, if pulverized waste material from siliceous ceramic products such as tiles and porcelain is used as the recrystallized silica component powder, the waste material can be effectively reused, which is preferable in terms of resource conservation. This product does not have problems such as strength loss or cracking, unlike products made by reusing defective cement-based building materials as aggregate.
