COMPARATIVE ANALYSIS OF THE MECHANICAL AND PHYSICAL PROPERTIES OF CONCRETE WITH ADDITION OF POLYMERS - BIBLIOGRAPHIC REVIEW

Abstract

Historically, concrete, understood as a construction material, is described as an artificial stone resulting from the junction of a binder with stone materials. Nevertheless, it can still be said that it may be as old as the very concept of civilization. When concrete is used as a structural material, it is called structural concrete, which can be of three different types: plain concrete without any kind of reinforcement; reinforced concrete when there is a non-pre-trained reinforcement. As for the general objective, it proposed to analyze the main mechanical and physical properties of concrete with the addition of vinyl acetate and polypropylene. The partial replacement of sand by polypropylene had an excellent performance regarding compressive strength due to the good densification of the polymer with the cement paste, low porosity. This is due to the good homogenization that the vibrating table provided to the specimens used in the test. The widely used correlation that the tensile strength of concrete corresponds to 10% of its compressive strength cannot be made freely. One of the main factors affecting the workability conditions of the mixture is the percentage of ethylene vinyl acetate (EVA) aggregate. The mixtures with 60% EVA showed the best results, and the 1:3 mixture presented a plastic consistency without segregation or floating of the aggregate. There is a sustainable potential in the search for alternative resources for making raw materials for civil construction.
