摘　　要：在自然养护的条件下,采用水泥-石灰-粉煤灰体系制备加气混凝土,研究了不同掺量的陶粒、矿渣、碱激发剂和水泥对加气混凝土力学性能的影响。研究结果表明:陶粒、矿渣和碱激发剂均能显著提高加气混凝土的强度,其中碱激发剂能使强度级别达到A05级,同时增加混凝土的干密度。增加水泥掺量,加气混凝土的强度和干密度均降低。In the natural curing, aerated concrete was manufacturing using cement-lime-fly ash system. The effects of different amount of ceramsite, slag, alkali-activator and cement temperature on the mechanical property of aerated con- crete were studied. It concluded that the ceramsite, slag and alkali-activator all can increase significantly the compressive strength and dry density of aerated concrete, the strength of concrete added alkali-activator can reach the level of A05. These aerated concretes with higher content of cement had less compressive strength and dry density.
