This paper investigates the impact of polymers on properties of white Portland cement pastes in the hardened state. Two different polymers, with different physical-chemical properties were used: EVA (ethylene vinyl acetate) as redispersable powder, and SAE (styrene acrylic emulsion). Pastes were prepared using a constant water/cement ratio of 0.40, and varying amounts of latex from 5% to 20% of actives by cement weight. Although the polymers had negative and different impacts on cement hydration reactions, the mechanical strength was increased; water absorption and steam permeability were reduced at a higher latex/cement ratio.
