煤渣小砌块是以水泥为胶结料,煤渣为骨料,掺入少量粉煤灰,经加水混合搅拌、成型机成型、自然(蒸汽)养护而成的一种新型墙体材料,具有轻质高强、保温隔热的特点。上海市普陀综合建筑材料厂从1993年开始生产煤渣小砌块,到目前为止,已生产350多万块,建造6层住宅10多万m~2。煤渣砌块受到用户的欢迎,取得了较好的经济、社会效益。 1 原材料及技术要求 The small cinder block is a new type of wall material made of cement as cement material, coal cinder as aggregate, small amount of fly ash, mixed with water by mixing, molding machine molding, and natural (steam) curing. High-strength, thermal insulation features. Shanghai Putuo Synthetic Building Materials Factory started producing cinder blocks in 1993. So far, it has produced more than 3.5 million blocks and constructed more than 100,000 m2 of 6-storey residential buildings. Cinder blocks are welcomed by users and have achieved good economic and social benefits. 1 Raw materials and technical requirements
