混凝土收缩的影响因素分析

Analysis of Factors Affecting Concrete Shrinkage

为研究影响混凝土收缩率的因素,分别配制了C35P8、C35P6、C40P6、C50等4种强度等级混凝土,按照空白、掺纤维、掺纤维和防水剂3种不同情况,对自然养护条件下3、7、14.28d龄期的混凝土收缩率进行比较,得出的结论可为工程的质量控制提供指导建议。

To study the factors affecting the shrinkage rate of concrete,four strength grades of concrete,C35P8,C35P6,C40P6 and C50,are prepared respectively.According to the three different conditions of blank,fiber,fiber and waterproof agent,the shrinkage rates of concrete at 3,7,14 and 28 days of age under natural curing are compared.The conclusions can provide guidance and suggestions for the quality control of the project.
