Properties of polymer-modified mortars made with blended cements

This Paper reports an investigation into the properties of polymer-modified mortars made with mixtures of Portland cement and ground granulated blastfurnace slag (GGBFS), microsilica (MS) and pulverized fuel ash (PFA). The polymer latex dispersion used was ethylene vinyl acetate (EVA). Workability, setting time, density, strength, permeability, drying shrinkage and adhesion were all measured, and of the blends tested only those using MS conferred advantages overall. Because of the generally slower development of strength, wet curing is necessary, and this is not satisfactory for EVA.
