Abstract
In this experimental study the effects of two types of polymers including ethylene vinyl acetate and styrene acrylic on the properties of cement mixtures have been investigated. Polymer contents of the mixtures were 5, 10, 15 and 20% by weight of cement and the ratio of water to cement was 0.33. In order to investigate and evaluate the effect of polymer materials on the properties mixtures, the compressive, flexural and tensile strengths, impact resistance, shrinkage, rapid chloride migration coefficient and the capillary water absorption contents were investigated. The specimens were cured under wet conditions at early ages (7 days) and dry periods at later ages (After 7 days). The results indicate an improvement in several mechanical characteristics such as flexural strength, tensile strength, impact resistance and a significant influence on reducing the permeability of cement mixtures in the rapid chloride migration and water absorption tests by use of polymers.
