摘　　要：以水泥、粉煤灰为主要原料,掺加适量激发剂、促凝剂和胶粉,利用自主研制的高效发泡剂,采用先独立发泡,再将泡沫与料浆混合的工艺方法制作水泥粉煤灰复合发泡轻质保温砌块,研究了砌块的生产工艺流程。进行了砌块试样制作,性能测试,结果表明,水泥粉煤灰复合发泡轻质保温砌块的干密度为318 kg/m3,28 d抗压强度为1.2 MPa,导热系数为0.088 W/m.K,各性能指标均满足GB/T 11969-2006《蒸压加气混凝土砌块》标准要求。A kind of foamer is introduced in the article,which made of the cement and fly ash as the main raw materials,and some additives of activator,coagulant and rubber powder.The process for production of block is also researched.On the basis of the optimal raw material formula determined in preparatory experiments,samples are made and tested;their performance reaches the requirement of the standard of GB 11969-2006 aerated-autoclaved concrete block.
