Análise de argamassas de reparo compostas por copolímero vinílico, PVA e SBR

This work aimed to develop and analyze polymeric repair mortars composed of either  vinylic copolymer, PVA (polyvinyl acetate), and or SBR (styrene-butadiene ). Tests were carried out to determine the compressive and diametral compression tensile strengths. In addition, the adhesive strength between the repair and the concrete was determined by means of a diametral compression traction test. Among the materials tested, it was noticed that the material modified by styrene-butadiene SBR hadexhibited the best performance, especially with respect to theits adhesion to the concrete. In general, the results showed that the mortars modified by the studied polymers can meet the function of a repair material
