摘要
Abstract
The rheological properties of compound pastes with large volume of ground granulated blast furnace slag ( GBFS ) mixed with 3 types of polycarboxylate superplasticizer were tested and comparatively analyzed by a nonlinear modified Bingham model. The results indicate that the relationship between rheological parameters and cement paste fluidity is a negative exponen-tial function or a liner function. Relative to common polycarboxylate superplasticizer, variation of cement paste fluidity exerts a higher impact on yield stress of the compound pastes mixed with early-strength polycarboxylate superplasticizer, but less impact on its plastic viscosity and thixotropy;in the case of same fluidity, the yield stress of compound pastes with ether-type polycar-boxylate superplasticizer is relatively smaller, while its plastic viscosity, thixotropy and maximum shear stress are larger.关键词
