This paper deals with the flexural and compressive strength properties of polymer-modified mortars with a garnet sand. Polymer-modified mortars with the garnet sand and three types of commercial polymer dispersions are prepared with various polymer-cement ratios and cement-sand ratios, and tested for flexural and compressive strengths. The polymer-modified mortars with a standard sand and a river sand are prepared, and tested for the same manner as the mortars with the garnet sand. It is concluded fom the test results that the water-cement ratio of the polymer-modified mortars at the same flow is markedly decreased by use of the garnet sand in place of the standard sand and river sand. The flexural and compressive strengths of the polymer-modified mortars with the garnet sand are larger than those with the standard sand and river sand. The flexural and compressive strengths of the polymer-modified mortars with the garnet sand tend to increase and decrease with increasing polymer-cement ratio, respectively.
