摘要
以粉煤灰为主要原料,同时添加水泥、石膏和生石灰等辅助原料,以十二烷基苯磺酸钠为发泡剂,采用浇注成型工艺制备了轻质墙体建筑材料。试验表明:随着粉煤灰含量的增加,试样抗压强度呈下降趋势,当粉煤灰掺量为40%时,试样的抗压强度最高,为14.4MPa;随着水泥含量的增加,试样抗压强度逐渐增加。
The lightweight wall building material was prepared by castable technology using fly ash as a major raw material, at the same time, adding a certain amount of cement, gypsum and calcined lime as auxiliary materials, and neopelex as blister. The results show that the compression strength is decreased with the increase of content of the fly ash. The compression strength has a maximum value 14.4MPa when dosage of fly ash is 40%. The compression strength has a raising trend with the increase of cement content.
