温湿度变化对加气混凝土砌块墙体收缩的影响研究

Research on the Influence of Temperature and Humidity Changes on the Contraction of Aerated Concrete Block Wall

加气混凝土墙体的开裂、渗漏等一直影响着加气混凝土的应用,引起加气混凝土墙体开裂的因素较多,但加气混凝土砌体干燥收缩往往被认为是引起墙体开裂的重要原因。运用加气混凝土砌块在不同温湿度的收缩情况下分析加气混凝土墙体材料在不同方向收缩的程度随时间变化的影响。研究出的成果可以用来指导减少收缩,既可增强生产实践,提高工程质量,也可有效促进加气混凝土墙体材料的推广。

The crack and leakage of aerated concrete wall has been affecting the application of aerated concrete. The causes of aerated concrete wall crack are various, but the aerated concrete masonry drying shrinkage is often considered as the important cause of wall cracking. The contraction of aerated concrete block in different temperature and humidity is different, which can be used to analyze the contraction degree of aerated concrete wall materials in different direction over time. The research results can be used to reduce shrinkage, which can enhance production practice, improve the quality of engineering, and can also effectively promote the promotion of aerated concrete wall materials.
