【摘要】 研究了用陶瓷粉末废料生产加气混凝土砌块的原料及配比、发泡剂用量、水料比和养护制度等因素,确定了最佳工艺参数。研究表明,在陶瓷粉末废料用量为73.5%、生石灰用量为18%、水泥用量为7%、石膏用量为1.5%、铝粉用量为0.9 kg/(m~3制品)、水料比为0.6、恒温蒸气压力为1.2~1.4 MPa的蒸压养护制度下,制备的加气混凝土砌块干密度小于560 kg/m~3,抗压强度大于3.7 MPa。更多还原

【Abstract】 The production of aerated concrete block using ceramic powder waste is studied in this work. Raw material proper-ties,raw material ratio,foaming agent dosage,water slurry ratio,and maintenance methods are discussed. The optimum process parameters are determined. When the content of raw materials is 73.5% of powder waste,18% of quick lime,7% of cement,1.5% of gypsum,and dosage of aluminite powder is 0.9 kg/m~3,water slurry ratio is 0.6,thermostatic steam pressure is 1.2~1.4 MPa,the produced aerated concrete block has the desiccated bulk density of less than 560 kg/m~3 and compressive strength of more than 3.7 MPa.更多还原
