Study on the Influence of Thickener on Rheological Parameters of Cement Paste and Properties of Concrete

The Influence of cellulose ether and polyacrylic acid thickener on rheological parameters of cement paste and properties of concrete were studyed. The results show that the incorporation of both thickeners can increase less plastic viscosity and more yield shear stress. With the increase of thickener content, the plastic viscosity and yield shear stress will Increase. The incorporation of two types of thickeners into concrete can effectively reduce the bleeding rate of concrete, the compressive strength at 3 d is slightly reduced, and the compressive strength at 28 d is slightly increased.
