水泥砂浆与混凝土干缩相关性研究

Correlation of drying shrinkage between cement mortar and concrete

本文通过试验测定掺与不掺矿物掺合料的水泥砂浆的干缩率及相应混凝土的干缩率,探讨水泥砂浆干缩与混凝土干缩的相关性,结果表明:水泥砂浆与混凝土的干缩符合二次多项式相关,且相关性良好。

By measuring the drying shrinkage of cement mortars and concretes with or without mineral admixture, the correlation of drying shrinkage between them is reviewed, The results indicated that there＇ s a good correlation of drying shrinkage between cement mortar and concrete to quadratic polynomial expression.
