Effect of Fineness on the Properties of Cement Paste

Abstract:

Properties of cement paste were affected significently by fineness of cement which is one of the most important influence factors. Effect of fineness on the rheology properties, strength, hydration and pore structure of cement was studied. The results showed that: plastic viscosity of the cement paste can be reduced by the increase of cement fineness to some extent. The strength of cement, especially the early strength significantly increased; heat of hydration increased, the peak of hydration heat brought forward and induction period shortened; porosity of cement paste reduced with the increase of cement fineness. There is a good negative linear correlation between characteristics particle size D (0.1) and 1 day hydration heat of three different kinds of cement. Keywords: cement; fineness; hydration; porosity
