介绍了多孔加气混凝土材料在饱和ＣａＣｌ２溶液中浸泡烘干后含盐量的实验结果；在实验基础上提出物理模型，找出材料含盐量随浸泡烘干次数、浸泡时间、温度、材料容重等的变化关系，证明了加气混凝土材料可作为吸温盐载体并对控制材料含盐量问题提出看法． The experimental results of the salt content of porous aerated concrete material after soaking and drying in saturated CaCl2 solution are introduced. Based on the experimental results, the physical model is proposed to find out the salt content of the material according to the number of soaking and drying, soaking time, temperature and material weight. The relationship between the changes, etc., proves that the aerated concrete material can be used as a carrier of temperature-absorbing salt and proposes opinions on controlling the salt content of the material.
