METHOD OF MANUFACTURING LIGHTWEIGHT AGGREGATE
To provide a method for producing a lightweight aggregate capable of suppressing the fusion of the lightweight aggregate at a low cost, in the production of a lightweight aggregate using coal ash as a raw material.SOLUTION: A method for producing a lightweight aggregate, comprises: a raw material preparation step for obtaining a lightweight aggregate raw material by mixing at least coal ash as a raw material and an anti-fusing agent containing a pulverized mold produced using foundry sand at a content of 60% by mass or less; a granulation step of granulating the lightweight aggregate raw material to obtain a granulated product; and a heating step of heating the granulated product to obtain a lightweight aggregate. The anti-fusing agent preferably contains a pulverized product of silica powder and foundry sand.SELECTED DRAWING: None
【課題】原料として石炭灰を用いた軽量骨材の製造において、低コストで軽量骨材の融着を抑制することができる軽量骨材の製造方法を提供する。【解決手段】原料として少なくとも、石炭灰と、鋳物砂を用いて製造された鋳型の粉砕物を６０質量％以下の含有率で含む融着防止剤を混合して、軽量骨材用原料を得る原料調製工程と、軽量骨材用原料を造粒して、造粒物を得る造粒工程と、造粒物を加熱して、軽量骨材を得る加熱工程、を含む軽量骨材の製造方法。融着防止剤は、好ましくは珪石粉及び鋳物砂の粉砕物を含むものである。【選択図】なし
