新にして、実効性をＭする成形方法の開示をその目的と
したものである。[Detailed Description of the Invention] This invention provides a novel and highly effective molding method for manufacturing various building materials, fitting materials, exterior materials, etc. using coal ash, so-called fly ash. Its purpose is disclosure.
而して、従前に於いては、石炭火力発電所から排出され
る石炭灰、所謂フライアッシュは、それが微細であり、
然も無機物であることにより、その処理に難渋していた
。Therefore, in the past, coal ash, so-called fly ash, discharged from coal-fired power plants was very fine.
However, since it is an inorganic substance, it has been difficult to process it.

に於いては比較的高価な材料を原料としており、石炭灰
の重要性は余り大きくない現状であり、又効果的な処理
方法をなかった＼め、コスト高であった。In addition, because the exhaust gas is a huge amount of food, it was hoped that industries that could use coal ash would become handmade, such as artificial lightweight aggregate, potash fertilizer, and building materials. In the industry, coal ash is still at the research and development stage, especially in the @ lumber industry, where relatively expensive materials are used as raw materials, and the importance of coal ash is currently not that great. There was no treatment method, so the cost was high.
