加气混凝土具有密度小,保温性能好,施工速度快和增加使用面积等优点,因而广泛用于建筑工程中。但加气混凝土干燥收缩值大,含水饱和抗冻性差,若对其特性不了解,设计或施工不当,则比其它墙体材料更易出现问题,在严寒地区尤为明显。本文针对寒冷地区应用加气混 Aerated concrete has the advantages of small density, good thermal insulation performance, quick construction speed, and increased use area. It is therefore widely used in construction projects. However, the aerated concrete has a large dry shrinkage value and poor water saturation and frost resistance. If it is not known about its characteristics and improper design or construction, it is more prone to problems than other wall materials, especially in severe cold regions. This paper applies aerated mixing for cold regions.
