Sažetak
Among the various latex modified mortars application, repair mortar is one of them. The purpose of this research is to investigate the mechanical properties of repair mortar modified with polymeric latex. The influence of Styrene-Butadiene-Rubber (SBR) latex (solid content 47 %) on commercial calcium aluminate cement’s (CAC) properties was observed. Mortar specimens with constant W/C ratio (0.4) and with different latex content (0 - 20 %) were prepared. Workability and air content entrapment in the mortar fresh state were investigated. In the hardened mortar state compressive and flexural strength, open porosity, density, and dynamic modulus at different curing age (1, 7 days and transformed specimens) were investigated. The test results showed that inclusion of SBR latex increased the workability and air entrapment of fresh state mortar and reduction in dynamic modulus and open porosity of hardened state mortar. Specimens with higher latex percentage at curing age of 7 days showed increment in bending strength, due to coagulation process of polymer.
