摘　　要：阐述了工业废渣混凝土多孔砖由于含水率降低引起的干燥收缩,是其建筑裂缝的主要成因之一,通过对混凝土多孔砖在自然温、湿度条件下从饱和含水率到趋于平衡含水率的失水及干缩情况及其砌体在中等湿度和干燥条件下干缩值的持续观测,得出其失水规律和干缩率。The paper describes that the drying shrinkage of the industrial waste concrete perforated brick caused by the low moisture content is one of main causes of the building crack, obtains the water losses rule and the dry shrinkage through the continuous observation of the water losses and the dry shrinkage of the industrial waste concrete perforated brick from the saturated water content to the equilibrium moisture content under the situation of the natural temperature and the humidity and the drying shrinkage value of the masonry under the situation of the middle humidity and the dry situation.

关 键 词：工业废渣混凝土多孔砖 墙体 干燥收缩
