外掺剂对混凝土干缩性能影响分析

Additive agent drying shrinkage of concrete performance impact analysis

自研究高性能混凝土的干燥收缩与自生收缩入手,进行系统地研究混凝土早期开裂问题。主要研究混凝土浆体的早期抗裂性能,参照《水泥混凝土砂浆体抗裂性能试验方法》,把混凝土早期抗裂问题简化成水泥浆体的抗裂行为进行具体分析。

Drying shrinkage of high performance concrete with spontaneous contraction of system were studied early cracking of con- crete problems. It mainly studied the early crack resistance of concrete slurry, with reference to the cement concrete mortar body crack resistance test method, to simplify the problem of concrete early crack into water slurry anti - cracking performance of concrete analysis.
