摘要
根据大流动性混凝土的流变学特点 ,采用自行设计的混凝土粘附系数测定装置 ,改变混凝土的水胶比、矿物掺合料掺量、外加剂掺量、砂率以及石子 砂浆比等配比参数 ,测定混凝土拌合物的粘附系数 。
We developed a new apparatus to measure the adhesion factor of the fresh concrete according to the rheological properties of high fluidity concrete in this study.Several factors ( W/B ,mineral admixture, A j, S p and the ratio of aggregates and mortar) affecting the adhesion factor were taken into account.And the changing tendency of adhesion factor with mixing ratio among different components was also studied.
