摘　　要：通过对刚出模的混凝土多孔砖进行了连续100 d收缩变形的试验研究.分析了在标准养护和自然养护环境条件下,环境温度、相对湿度及龄期等因素对混凝土多孔砖收缩变形的影响,并提出了考虑这些因素的混凝土多孔砖收缩变形的估算公式.这项研究结果可为解决我国混凝土多孔砖工程中墙体开裂问题提供参考依据.Based on the test results for the dry shrinkage deformation of concrete perforated bricks within 100 days. Cured in the standard environment and the natural environment, the main factors affecting the shrinkage deformation such as the ambient temperature, the relative humidity and the curing ages are discussed and analyzed. The formulas which considented these factors are suggested, and this may be as a reference for the application of concrete perforated bricks wall＇s crack in engineering.
