Research on the Rheology of Polymer latex Modified Cement Paste Containing Mineral Admixtures

摘要：

　　The rheology of styrene-butadiene rubber (SBR) polymer latex modified cement paste (SMCP) was studied in this paper.The effects of mineral admixtures (MAs) on the rheological performance of SMCP were studied using the Brookfield R/S Plus rheometer.The results indicate that the plastic viscosity of SMCP with different shear rate all decreases as the test time extends.As the shear rate increases,the plastic viscosity reduces significantly.The rheology of SMCP improves as the SBR latex content gradually increases.With increasing quantities of fly ash (FA),the yield stress of SMCP gradually increases and the plastic viscosity also increases to a certain extent.However,with a gradual increase in the granulated blast-furnace slag (GBFS) content,the yield stress and plastic viscosity of the SMCP decrease unobviously.
