摘　　要：目前,混凝土小型空心砌块得到了广泛的应用,由它引起的墙体裂缝问题也得到了人们的关注。通过自行设计的保湿空间,对尺寸相同、构造措施不同的砌块墙体进行试验,分析了环境相对湿度、上墙后时间、面层材料等因素对砌块墙体变形的影响,对比了不同面层材料的抗变形效果,并测得相对湿度分别为65%、45%条件下墙体的干缩率,可供工程应用参考。At present small concrete hollow block has been used popularly and attention has been paid to problem of its wall cracking.Experiments have been made on the block walls with different structures and same dimension by self-designed moisture space,analyzed influence of factors such as ambient relative humidity,time af-ter blocks on the wall,surfacing material etc.on deformation of block wall,compared anti-deformation effect with different surfacing materials and measured dry shrinkage of the wall under two moisture conditions of65%and45%that can be used as reference for engineering.

关 键 词：混凝土小型空心砌块墙体 裂缝 保湿空间 干缩率
