The influences of temperature on structure of fresh cement paste with low shear rate were studied and the measurements of rheological curve were approached by means of the RHEORIAB QC type rotational viscometer. The results show that the distinction of elasticity, plasticity and viscosity of cement paste and the static yield stress depend on the shear rate, elasticity, plasticity and viscosity of cement pastes which can be effectively distinguished at the shearing rate of 01s-1. The increasing shear stress partly reflects the hydration of cement pastes. When temperature rises, elasticity, plasticity and viscosity of cement pastes increase, the initial static yield stress and storage modulus increase. Along with the hydration of cement pastes, when shear stress of cement pastes increases once again with the increase of temperature the time required will decrease linearly and both shear stress of cement pastes and their increasing rate increase with the rising temperature.
