摘 要:通过抗压强度、非蒸发水量、矿渣反应度的试验测定及XRD分析,研究了掺矿渣水泥浆体的水化反应进程。结果表明,在相同龄期下,抗压强度随矿渣掺量与水胶比的增加呈减小趋势,矿渣的化学活性在28d前比较显著;掺矿渣水泥浆体的非蒸发水量高于纯水泥浆体非蒸发水量;矿渣的反应度则随其掺量的增加而减小,随水胶比的增加而增大。
Abstract: Though the testing methods of compressive strength, non-evaporable water content, reaction degree of slag and XRD-analysis, the hydration process of cement paste with slag was studied. The results showed that at the same age, the compressive strength will decrease along with the increasing of water binder ratio and the centent of added slag. The chemical activity of slag is rather obvious in the 28d ages. And the content of non-evaporable water of cement paste with slag is higher than that of cement paste without slag. The reaction degree of slag decreased along with the increasing of content of added slag, and it increased along with the increasing of water binder ratio.
