摘　　要：在我国,建材生产能耗、建筑物建造使用过程中能耗比例约占社会总能耗的46.7%;目前,国内大多数建筑墙体的传热系数较高,而且很容易吸收太阳能辐射;外墙内保温存在冷(热)桥问题;再者我国限制生产、使用黏土实心砖的力度逐渐加大。以砂加气混凝土砌块为主要替代产品的新型墙体节能材料得到了迅速的发展,且具有广阔的市场发展空间。对加气混凝土所具有的良好保温隔热性能、应用发展现状以及加气混凝土节能发展前景做出综述,对节能加气混凝土的进一步发展和推广提供一些有益的参考。In our country, energy consumption of building materials ,building construction in the process of using the energy consumption proportion account for about 46.7% of total energy consumption of society; nowadays, most of the domestic building wall heat transfer coefficient is high;furthermore, it is easy to absorb solar radiation;since our govemment limited the produce and the use of solid clay brick, sand aerated concrete block has acted as the main product to replace the new energy-saving wall materials,obtaining the rapid development.It has a broad market space for development.This emphasizes on the good thermal insulation properties of aerated concrete, and its development and present status of the application and energy saving development prospects, in order to provide some useful reference of energy-saving aerated concrete for further development and oromotion.
