Abstract：Based on a closely packed grading model,the effect of the grading distribution modulus on the rheological properties of composite cementitious material paste was studied.The results show that the effect of grading distribution modulus of the Dinger-Funk model on the yield stress and plastic viscosity of different composite pastes varies.The rheological properties of pastes are correlated with its wet packing density to a certain extent,and the water film thickness is a key factor affecting the rheological properties of the pastes through the grading distribution modulus.As the water film thickness increases,the yield stress and plastic viscosity of composite cementitious materials paste decrease in a power exponential manner.This effect can be represented by the simplified YODEL model and Ahmadah model.
