Viscosity of high-flowing concrete is important rheological property that dominate the flowability of concrete. Supposing that mix proportion and slump flow of concrete is constant, the viscosity varies with the temperature of concrete and influence on segregation or rate of placing of fresh concrete. In this study, influences of the temperature on rheological properties of cement paste in high-flowing concrete was investigated. It is confirmed that interrelationship between yield value and plastic viscosity of fresh cement paste changed with temperature and that the temperature of paste became lower, the viscosity became larger. Furthermore, this mechanism could be explained DLVO theory with due regard to change in adsorption capacity of superplasticizer with temperature.
