摘　　要：为解决大掺量固硫灰蒸压加气混凝土坯体蒸压养护时,水分含量过高导致砌块产品质量下降的问题,试验以固硫灰为主要原料制备B06A3.5蒸压加气混凝土砌块,优化恒温温度、升温速率、恒温时间等工艺条件。结果表明:当固硫灰掺量为70%、水料比为0.95时,最优蒸压养护制度为恒温温度179.5℃、升温速率109.6℃/h、恒温时长3.03h。In order to solve the problem that the high moisture content in autoclaved aerated concrete billet with large dosage of sulfur ash leads to the quality decline of block products during autoclaved curing,this experiment used sulfur fixing ash as the main raw material to prepare B06 and A3.5 autoclaved aerated concrete blocks,and optimized the process conditions of constant temperature,heating rate and constant temperature time series.The results show that when the content of fixed sulfur ash is 70%and the water material ratio is 0.95,the optimal autoclave curing system is a constant temperature of 179.5℃,a heating rate of 109.6℃/h,and a constant temperature duration of 3.03h.
