加气混凝土比泡沫混凝土的生产工艺简单,沉陷变形小,甚至可浇灌1.2m高的制品(泡沫混凝土料浆高达0.5m就发生沉陷)。用1∶1水泥与石灰配制的加气混凝土,2小时以后,其塑变强度可达60g/cm~2,而同样成分的泡沫硅酸盐,须经过9小时才能达到这样的塑变强度。用石灰生产的加气硅酸盐,对钢筋的锈蝕、大气稳定性、抗冻性,比以水泥为原料的加气混凝土差。但在加气硅酸盐中掺加部分水泥,就可大大改善其性能。如加气硅酸盐的大 Compared to foamed concrete, aerated concrete has a simpler production process with less subsidence and can even be poured with 1.2m high products (subsidence occurs when foamed concrete slurry reaches 0.5m). Aerated concrete formulated with 1:1 cement and lime, after 2 hours, its plastic deformation strength can reach 60g/cm~2, and foam silicate of the same composition must reach 9 hours to reach such plastic strength. Liquefied silicates produced from lime have poor corrosion, atmospheric stability, and frost resistance to rebar compared to aerated concrete made of cement. However, adding some of the cement to the air-entrained silicate can greatly improve its performance. Such as the addition of large silicates
