晶种与盐复合对混凝土早期强度的影响

本文将高价阳离子硫酸盐、有机盐分别与晶种复合,检验其对混凝土早期强度的影响。试验表明,这两种复合早强剂对混凝土早期强度的作用效果都十分理想。这两种经过最佳的配比复合后的外加剂都能使混凝土的3d强度比单掺晶种提高20%以上,且对混凝土的后期强度无不利影响。

The high valence cation sulfate and organic salt is compounded with crystal seed separately in concrete for detecting the effect on the early strength of concrete in this article.Experimental results show that the two compounded hardening accelerator admixtures are good to concrete early strength, under an ideal mix ratio,they can both make the concrete strength of 3 day increase more than 20%,and had no unfavourable effect on the latter strength of concrete.
