Polymer modified mortars using either recycled waste concrete fine aggregate (WCFA) or artificial marble waste fine aggregate (AMWFA) were prepared and investigated for the purpose of feasibility of recycling. The replacement ratio of recycled materials also changed to investigate the effect of it on mechanical and physical properties. The water.cement ratio was increased as the replacement ratio of either AMWFA or WCFA in mortar in the absence of styrene-butadiene rubber (SBR) latex. The presence of SBR for both WCFA and AMWFA gave the increase of the air content. The compressive strength decreased in the presence of SBR. The higher replacement ratio of WCFA and AMWFA lowered the compressive strengths significantly. The compressive strength ofAMWFAwas significantly lowered after the hot water resistance test, whereas that of WCFA was slightly increased after the hot water resistance test. As the replacement ratio of either WCFA or AMWFA increased, the flexural strength decreased as well as compressive strength.
