摘　　要：针对建材市场节能环保产品的需求,加气混凝土制品以其独特的质轻节能、保温隔热、抗震隔音等综合性能优势而备受关注。简述了蒸压加气混凝土的制备过程,重点阐述了制备加气混凝土砌块的硅质材料、钙质材料、发气剂、水料比及添加物等物料特性对制品性能的影响,介绍了坯体养护条件、制备过程反应以及制品微观结构对加气混凝土性能的影响机理,展望了加气混凝土未来的发展方向。Aimed at new requirements brought up by domestic building material market, autoclaved aerated concrete has been acclaimed owning to its several particular performance advantages such as lightweight, thermal insulation, acoustic insulation, anti-seismic, etc. After preparation process of auto-claved aerated concrete was briefly summarized, it focused on influence of material characteristics on the properties of the products such as siliceous material, calcareous material, vesicant, water-solid ratio and ad-ditives. Influence mechanism of curing conditions of green body, reaction process of preparation and prod-ucts microstructure on performance of autoclaved aerated concrete were introduced. Eventually, direction of development of autoclaved aerated concrete was prospected in the future.
