摘要
对不同条件下混凝土多孔砖砌体墙进行连续60 d干燥收缩变形试验,分析了砌筑砂浆、龄期、混凝土多孔砖初始含水率、相对湿度和温度对混凝土多孔砖砌体墙收缩的影响,并提出了标准养护及非标准养护条件下混凝土多孔砖砌体墙收缩率估算公式,研究结果可为混凝土多孔砖在我国北方地区应用提供参考依据。
Based on the results for the dry shrinkage deformation of concrete perforated brick masonries cured under different conditions for continuous 60 days,the main factors affecting the dry shrinkage deformation,such as bricklaying motor, the curing ages,the initialization moisture content,the relative humidity and temperature were analyzed. The formulas estimating the dry shrinkage deformation of concrete perforated brick masonries under the standard curing condition and the natural environment are put forward. The study results may be a reference for the application of concrete perforated bricks in north regions.
