FRP products have been widely used in various fields of industry because of possessing high-strengths, corrosion resistance. Accordingly the waste FRP have also been increased and the effective recycling methods of waste FRP are needed. In this study, polymer mortar specimens were prepared with the various substitution amount of waste FRP powder. For finding the mechanical properties of polymer mortar added with waste FRP powder, compressive strength tests are conducted. From the test, we could find that compressive strength was increased with respect to the amount of waste FRP powder.
