摘要
用旋转黏度计和微型坍落度仪测定水泥浆体的流变性,又利用岩相分析、XRD、水化热等测试方法分析相关的作用机理,研究探讨煅烧气氛对水泥浆体流变性的影响。结果表明,在还原气氛下煅烧的熟料,其中的Fe2O3部分被还原为FeO、FeS,因而减少了C4AF含量,增大了C3A含量,使得水泥的水化速度加快,浆体的流变性降低。
The rheological property of cement paste was measured by rotatory viscometer and micro slump meter cone,and the mechanisms that influence the rheological behavior of cement paste were analyzed by means of petrographic analysis,XRD and hydration heat measurement.The effect of kiln atmosphere on the rheological property of cement paste was studied.The results showed that some Fe2O3 in clinker would be reduced to FeO and FeS in the reductive atmosphere,so the content of C4AF decreased and that of C3A increased.Consequently the hydration of cement would be accelerated,then the rheological property of cement paste would be changed.
