In this study, the purpose of this study was to understand the effect of increasing the load carrying capacity against negative bending when PPC was used to increase the thickness of the floor slab. Load test of RC beam reinforced with carbon fiber reinforced plastic (CFRP lattice) and PPC was performed. PPC is a mixture of unsaturated polyester resin and aggregate mixed and cured. As a result, the strength calculation by the RC design method is effective for PPC, a large reinforcement effect by PPC was confirmed, and the adhesion performance of PPC was very excellent, and no delamination occurred at the interface. It was mentioned that the end was reached.
