PRODUCTION METHOD OF BURNED PRODUCT
PROBLEM TO BE SOLVED: To provide a simple method capable of obtaining a burned product of a low absolute dry density (for example, 1.0 g/cmor lower).SOLUTION: A production method of a burned product includes a burning step for producing a burned product by burning particles of a size of 10-50 mm or less made of a composition containing a powdery material containing coal ash and cement, a foaming agent made of iron oxide, and water. The composition preferably contains the coal ash of 50-97 mass%, the cement of 2-20 mass%, and the foaming agent of 1-10 mass% each relative to the total amount of the powdery material and the foaming agent, and water of 3-50 pts.mass relative to 100 pts.mass of the powdery material. Preferably, heating temperature is 1,100-1,400°C in the burning step and the obtained burned product has an absolute dry density of 1.0 g/cmor lower.SELECTED DRAWING: None
【課題】簡易な方法で、絶乾密度の小さい（例えば、１．０ｇ／ｃｍ３以下）焼成物を得る方法の提供。【解決手段】石炭灰およびセメントを含む粉状材料と、酸化鉄からなる発泡剤と、水とを含む組成物からなり、かつ、粒度が１０〜５０ｍｍの粒体を焼成して、焼成物を得る焼成工程、を含む焼成物の製造方法。粉状材料と発泡剤の合計量中、石炭灰の割合は、好ましくは５０〜９７質量％、セメントの割合は、好ましくは２〜２０質量％、発泡剤の割合は、好ましくは１〜１０質量％であり、かつ、水の量は、粉状材料１００質量部に対して、好ましくは３〜５０質量部である、焼成物の製造方法。好ましくは、前記焼成工程における加熱温度が１，１００〜１，４００℃であり、得られた焼成物の絶乾密度が１．０ｇ／ｃｍ３以下である、焼成物の製造方法。【選択図】なし
