摘　　要：加气混凝土作为一种轻质材料，在建筑维护结构中的应用越来越广泛，然而，加气混凝土与抹面砂浆的匹配性也越来越受重视。本文对加气混凝土与界面砂浆的匹配性展开探讨，发现加气混凝土与砂浆的组合砌体，在含水率大于15％时，组合砌体与原加气混凝土砌块的收缩值没有显著的差异，在含水率小于15％范围内，组合砌体的干燥收缩值小于原砌块，约占其90％。组合砌体的粘结力随掺合料掺量的增加而降低。减少掺合料的掺量，能够提高界面砂浆的粘结强度。as a kind of light material, aerated concrete is more and more wide using in building maintenance structure, so the adaptability problem is more and more important. The author find the fact that when moisture content is more than 15%, the combination blocks with aerated concrete and mortar and aerated concrete block is not significant difference, but when moisture content is less than 15%, the drying shrinkage of combination blocks is less than aerated concrete, is about 90%. The cementing bond of combination blocks decrease with increase of admixture. The bond strength can improve reducing the admixture.
