RAW MATERIAL COMPOSITION OF ALUMINOSILICATE CURED BODY AND CURED BODY USING THE SAME
PROBLEM TO BE SOLVED: To provide a raw material composition which contains carbon and nonetheless, enables an aluminosilicate cured body having reduced irregular color due to the carbon to be produced, and to provided an aluminosilicate cured body using the raw material composition.SOLUTION: The raw material composition of an aluminosilicate cured body is provided that contains burnt ash containing silica, alumina and unburned carbon, an alkali metal salt and an additive and the additive is one or more of naphthalenesulfonic acid-based and polycarboxylic acid-based. The additive is preferably contained in an amount of 2.9 to 46.0 mass% by a ratio to the unburned carbo in the total solid content. Further the burned ash is preferably one or more kind of coal ash, paper making ash, slurry ash and biomass boiler ash. Further an antifoam agent preferably is contained. The invention also provides an aluminosilicate cured body formed from a raw material composition.SELECTED DRAWING: Figure 1
【課題】原料にカーボンが含まれていても該カーボンによる色斑が低減されたアルミノケイ酸塩硬化体を製造することができる原料組成物と、それを用いたアルミノケイ酸塩硬化体を提供する。【解決手段】シリカとアルミナと未燃カーボンを有する焼成灰と、アルカリ金属塩と、混和剤とを含有し、該混和剤は、ナフタレンスルホン酸系、ポリカルボン酸系のいずれか１種以上であることを特徴とするアルミノケイ酸塩硬化体の原料組成物。混和剤を全固形分中の未燃カーボン量対比で２．９〜４６．０質量％含有することが好ましい。更に、焼成灰は、石炭灰、製紙灰、汚泥灰、バイオマスボイラー灰のいずれか１種以上であるであることが好ましい。更に、消泡剤を含有することが好ましい。また、本発明は、前述した原料組成物から形成されたアルミノケイ酸塩硬化体も提供する。【選択図】図１
