加气混凝土的结构与性能研究进展

A Review on Structure and Properties of Aerated Concrete

加气混凝土是一种新型的自保温墙体材料,其性能取决于材料的结构和化学组成。简述了加气混凝土的分类,综述了国内外加气混凝土在材料结构(孔隙率和孔径分布)、水化产物、物理性能和使用性能等方面的最新研究进展,并对它们之间的关系进行了探讨。最后,针对加气混凝土的生产和工程应用实际,阐述了加气混凝土今后的研究方向和研究重点。

Aerated concrete has outstanding performance on energy saving, materials saving and industrial solid wastes reusing. The performance of aerated concrete depends on its microstructure （pore system and the gel system） and chemical composition, which are affected by the type of binder, methods of pore formation and curing. The research progress of aerated concrete on its physical structure, chemical composition, mechanical properties and functional characteristics is reviewed,and the future research directions and emphasis are discussed.
