The aim of these experiments was to contribute to the understanding of the mutual influence of polymer and cement during the hardening of the combined system. Polyvinylacetate as water-emulsion was chosen as representative of polymers for all experiments. This paper deals with the results of the experiments with polyvinylacetate-modified cement mortars; the effects of polymer admixtures on compressive, tensil, and flexural strength; on mudulus of elasticity; the effect of relative humidity; and of polymer plasticizer on shrinkage. The dependence of strength on dimension of test specimens and the behavior of theis mortar in water exposure and in weatherometer, rapid-cycle exposure are discussed. Consideration of the results suggests fundamental ideas about the structure formation of polymer-cement mixtures.
