| 摘 要： | 对混凝土多孔砖试块进行了连续60d干燥收缩变形的试验，通过对其在标准养护和自然养护环境中收缩性能的研究，分析了环境温度、相对湿度及龄期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估算公式。研究结果可为我国混凝土多孔砖在工程中的应用提供参考依据。

| Abstract: | Based on the test results for the dry shrinkage deformation of concrete perforated bricks cured in the standard environment and the natural environment within 60 days,the main factors affecting the dry shrinkage deformation such as the ambient temperature,the relative humidity and the curing ages are discussed and analyzed. The formulas which estimated the dry shrinkage deformation of concrete perforated bricks are suggested,and this may be as a reference for the application of concrete perforated bricks in... |
