Rheological constants measurement of cement paste and cement paste flow analysis by marker particle visco-plastic finite element method

Abstract

In this study, the flow curve of cement paste was obtained by using a rotational viscometer for the purpose of expressing the flow characteristics of cement paste. The rheological constant was obtained by approximating this flow curve by Bingham model. Using the obtained rheological constants as input values, the cement paste flow test results were analytically reproduced by the proposed marker particle viscoplastic finite element method. The results obtained by the analysis agreed well with the experimental results. Therefore, it was found that the marker particle visco-plastic finite element method and the rheological constants obtained by the experiment are effective.
