在试验室进行大掺量脱硫粉煤灰制备蒸压加气混凝土的探索试验基础上,进一步研究掺加分散剂和表面活性剂等外加剂对加气混凝土性能的影响。实验结果显示,掺加0.7%~1.0%的六偏磷酸钠分散剂,0.5%~0.7%的焦磷酸钠表面活性剂,蒸压加气混凝土制品的干密度、抗压强度性能可以得到优化。 On the basis of the exploratory experiments on preparing autoclaved aerated concrete with large amount of desulfurized fly ash in the laboratory, the effects of additives such as dispersant and surfactant on the properties of aerated concrete were further studied. The experimental results show that the dry density and compressive strength performance of autoclaved aerated concrete products can be optimized by adding 0.7% ~ 1.0% sodium hexametaphosphate dispersant and 0.5% ~ 0.7% sodium pyrophosphate surfactant.
