摘　　要：我国磷石膏、脱硫灰、废土等工业固体废物堆存量巨大,利用率不足,含有污染物,对环境安全具有潜在风险。通过配合比设计、原料预处理、气泡调节和多温段养护等工艺,成功制备出具有优异功能的高掺合固废功能性蒸压加气混凝土板,原料最佳配比为磷石膏:废土:脱硫灰:水泥:石灰=8:50:20:10:12,干燥质量比75%,板的抗压强度5.2MPa,标准干密度606kg/m3,干燥收缩值0.36mm/m。In China,phosphogypsum,desulfurization ash,waste soil and other industrial solid wastes are huge and underutilized,because they contain pollutants,there are potential risks to environmental safety.In this study,a high-blended solid waste functional prefabricated autoclaved aerated concrete slab with excellent functions is successfully prepared through the processes of mix ratio design,raw material pretreatment,bubble adjustment and multi-temperature curing,and the optimal ratio of each raw material was phosphogypsum:waste soil:desulfurization ash:cement lime=8:50:20:10:12,the dry mass ratio is 75%,the compressive strength of the plate is 5.2MPa,the standard dry density is 606kg/m^(3),and the dry shrinkage value is 0.36mm/m.
