【摘要】 基于紧密堆积级配模型，研究了级配分布模数对复合胶凝材料浆体流变性能的影响.结果表明：Dinger-Funk模型级配分布模数对不同复合胶凝材料的屈服应力和塑性黏度具有不同的影响规律；浆体流变性能与湿堆积密实度存在一定的相关性，而水膜厚度是级配分布模数影响浆体流变性能的关键因素；随着水膜厚度的增加，复合胶凝材料浆体的屈服应力和塑性黏度呈幂指数型下降趋势，这一影响可通过简化YODEL模型和Ahmadah模型体现.更多还原

【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.更多还原
