Research on the Effect of Polycarboxylate Superlasticizers on Reheology Properties of Compound Cementitious System

Article Preview

The rheological property is the best method which can directly reflect the dispersion property of polymer surfactants. In this paper, the rheological properties in the systems of pure cement, cement/fly ash and cement/silica fume with polycarboxylate superplasticizers of different molecular structures were studied. The effect of molecular structure on shear sress, apparent viscosity and thixotropy in compound cementitious systems was expatiated. At last, the rules of mineral admixture to the system’ rheological property and the relations between adsorption amount and rheological properties were put forward.
