Rheological Investigation into Compatibility of Cement and Superplasticizers

Wu Xiao-mei Wen Zi-yun Fan Yue-ming(School of Materials Science and Engineering,South China University of Technology,Guangzhou 510640,Guangdong,China)  
By investigating the influences of the water-to-cement ratio,the superplasticizer type and the cements manufactured by different factories on the compatibility of cement and superplasticizer and on the rheological pro-perties of cement paste,the relationship between the compatibility and the rheological properties is revealed,and the rheological principle of compatibility is defined.The results show that the rheological characteristics of the cement paste adding superplasticizer accord with the normal Bingham model or the Newtonian model,that the Marsh cone fluidity synthetically reflects both the yield stress and the viscosity coefficient of the paste,and that the superplasticizer dosage and the Marsh time at the saturation point represent the smallest dosage of superplasticizer at the down limits of yield stress and viscosity coefficient,and the smallest viscosity coefficient,respectively.
