摘要
在混凝土配合比设计初期,通过对不同配合比混凝土收缩的对比试验,分析了不同细骨料细度模数、砂率、矿物掺和料掺量等对混凝土收缩的影响,并结合实际施工效果提出了有效减小混凝土收缩,提高混凝土耐久性的方法.
In the early mix design of concrete,through the comparative shrinkage tests on different mix proportions of concrete,this paper analyzed the influences of different fine aggregate moduli,sand ratios and mineral admixture contents on its contraction and,based on the practical construction effects,presented relevant approaches effectively to reducing its shrinkage and enhancing its durability.
