混凝土收缩的影响因素很多,国内外很难对混凝土收缩做出比较客观的定量描述。即使做出相关的定量描述,也由于影响因素众多且大部分影响因素与材料相关,结构设计人员很难应用,不利于公式的推广。本文对我国商品混凝土的配合比进行调研,通过调查结果,分析我国混凝土配合比的特点。最后按照最常用的配合比配置混凝土,对其干燥收缩进行分析研究。
Concrete shrinkage of many factors, it is difficult at home and abroad to make concrete shrinkage more objective and quantitative description. Even if the relevant quantitative description is made, the structural designers are hard to apply because of the large number of influencing factors and most of the influencing factors are related to the materials, which is not conducive to the promotion of the formula. In this paper, the proportion of China’s commercial concrete mix to conduct research, through the survey results, analysis of the characteristics of China’s concrete mix. Finally, according to the most commonly used concrete mix configuration, analysis of its drying shrinkage.
