Abstract

In this study, the shear box tests are carried out with cement paste in order to quantify the rheological constants. The materials have four level of water-cement ratios in $0.30\~0.45$, with or without high-range water-reducing AE agent. As the results, it was clarified that the rheological constants of cement paste are dependent on the value of shear strain, and the incremental coefficient of yield value is varied with the water-cement ratio and the dosage of high-range water-reducing AE agent.
