In order to recycle the FRP wastes from SMC bathtubes, polymer-modified mortars containing a fine powder of fiber-rainforced plastics(FRP) as a part of the sand were prepared with various FRP replacements for sand and polymer cement ratios. The polymer modifier used was polyacrylic ester(PAE) emulsion. The FRP waste fine powder was obtained by pulverizing FRP Wastes. The the mortar were tested and the results compared to those of ordinary cement mortar and polymer-cement mortar. As the results, compressive and flexural strengths of ordinary portland cement mortars containing FRP Wastes fine powder were remarkably decreased with an increase of a content of FRP wastes fine powder. But those strengths of ordinary portland cement mortars were greatly improved by adding PAE emulsion. When the replacement ratios of FRP wastes fine powder and adding ratios of PAE emulsion were 5, 10, 20wt% and 10, 15, 20wt% respectively, the compressive and flexural strength of PAE-modified mortar containing FRP wasted fine powder were showed as much those strengths of ordinary portland cement mortar. Otherwise heat curing of PAE-modified mortar containing FRP wastes fine powder accelerated the improvement of early compressive and flexural strengths. But the compressive and flexural strengths of PAE-modified mortar containing FRP wastes fine powder were remarkably decreased after hot water immersion test.
