与普通混凝土相比，加气混凝土是相对均匀的，因为它不包含粗骨料相，但其性能表现出巨大的变化。加气混凝土的性能取决于其微观结构（空隙-浆体系统）和成分，而这些又受到所用粘结剂类型、成孔方法和养护方法的影响。虽然加气混凝土最初被认为是一种良好的隔热材料，但由于其重量较轻、节省材料和大规模利用诸如粉煤灰等废物的潜力，人们对其结构特性重新产生了兴趣。本文的重点是对加气混凝土的物理（微观结构，密度），化学，机械（压缩和拉伸强度，弹性模量，干燥收缩）和功能（隔热，水分传输，耐久性，耐火性和隔音）特性的研究进行分类。(C)2000爱思唯尔科技有限公司版权所有。
Aerated concrete is relatively homogeneous when compared to normal concrete, as it does not contain coarse aggregate phase, yet shows vast variation in its properties. The properties of aerated concrete depend on its microstructure (void-paste system) and composition, which are influenced by the type of binder used, methods of pore-formation and curing. Although aerated concrete was initially envisaged as a good insulation material, there has been renewed interest in its structural characteristics in view of its lighter weight, savings in material and potential for large scale utilisation of wastes like pulverised fuel ash. The focus of this paper is to classify the investigations on the properties of aerated concrete in terms of physical (microstructure, density), chemical, mechanical (compressive and tensile strengths, modulus of elasticity, drying shrinkage) and functional (thermal insulation, moisture transport, durability, fire resistance and acoustic insulation) characteristics.
