Abstract

According to the evaluation of basic properties and mechanical characteristics of polymer cement mortars that contain re-dispersible type polymer, in the case of fresh mortars, flow and air content were increased due to the dispersion action of entrained air and surfactant with an increase of polymer addition ratio. In the case of mortars after hardening, flexural strength, bonding strength, absorption rate and carbonation resistance were improved due to the increased union and waterproof characteristics of internal structures as a result of the formation of polymer film.
