前言蒸压加气混凝土是这样一种多孔材料,其胶结材料是水化硅酸钙。可由各种原材料如水泥、石灰、粒状高炉矿渣、砂及粉煤灰制成。多孔结构一般由混合料中铝粉形成,铝粉与石灰或其他碱性物质反应生成氢气,使混合料膨胀,膨胀后的加气混凝土在切割与蒸压处理之前必须硬化几小时。 Introduction Autoclaved aerated concrete is a porous material whose cement material is hydrated calcium silicate. It can be made from various raw materials such as cement, lime, granulated blast furnace slag, sand and fly ash. The porous structure is generally formed from the aluminum powder in the mixture. The aluminum powder reacts with lime or other alkaline substances to generate hydrogen, which expands the mixture. The expanded aerated concrete must be hardened for several hours before cutting and autoclaving.
