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.
Abstract:
The experimental study of continuous shrinkage deformation of perforated concrete bricks that have just been molded for 100 days was carried out. The effects of ambient temperature, relative humidity and age on shrinkage and deformation of concrete perforated bricks under standard conservation and natural conservation environmental conditions were analyzed. An estimation formula for shrinkage deformation of concrete porous bricks considering these factors is proposed. This study result can provide a reference for solving the problem of wall cracking in concrete perforated brick engineering in China.
