采用活化石灰 ,活化粉煤灰和外加剂等综合技术途径 ,制备具有容重小于1000kg/m3 抗压强度大于15MPa的高强度加气混凝土。研究表明 ,活化石灰、活化粉煤灰可加速加气混凝土在蒸压养护过程中的水热合成反应 ,明显提高制品的强度。这种加气混凝土制品可代替粘土砖用于承重砌体结构 Activated lime, activated fly ash and additives and other integrated technical approach to prepare a bulk density less than 1000kg / m3 compressive strength greater than 15MPa high-strength aerated concrete. The research shows that activated lime and activated fly ash can accelerate the hydrothermal synthesis reaction of aerated concrete during the autoclave curing process and obviously improve the strength of the product. This aerated concrete product can replace clay brick for load-bearing masonry structure
