Abstract

In this paper, steel slag powder, slag powder and fly ash mixed with different proportions, equivalent replacement of cement, as concrete admixture, study the effect of the admixture on the performance and mechanical properties of concrete, and through the XRD, SEM, differential thermal and other micro testing means, discusses its hydration characteristic. The results show that: when the total amount of the admixture is less than 40%, the increase of its total content is beneficial to improve the working performance and mechanical properties of concrete, and the best ratio is steel slag powder: slag power: fly ash =1:2:1. The results of the study have found that the hydration products of the cementitious materials are the same as that of the pure cement. Early, cementitious materials activity are low, but later, under Ca(OH)2 excitation, cementitious materials began to hydrolysis, produce hydrated calcium silicate, hydrated calcium aluminate, and the hardened paste structure is more dense.
