Abstract
Polycarboxylate comb-like copolymer (PCE) is a kind of polyelectrolyte, which is easily affected by the ions in cement suspensions. In this work, the effects of sulphate ion on the surface charge, adsorption and dispersion in cement system with PCE as dispersant were investigated in detail. The addition of sulphate ion apparently decreased the positive charge on the surface of cement particles. The sulphate ion reduced the adsorption and dispersibility of PCE in cement suspensions, which was due to the competition between sulphate ions and PCE in the adsorption behaviour on the surface of cement particles. 11 Refs.
