The objective of this study is to understand the flexural reinforcement effects of RC slab reinforced with HFRP plate. To this end, an experiment was conducted by fabricated five RC slabs with the variables such as the number of anchors, epoxy injection amount and position. The Strength formula calculation on the specimens, was calculated to apply the ACI 440.2R-08(10.2.10). The results of this study, the stiffness, strength and structural performance of reinforced specimens are appeared very high compared with non-reinforced specimen, so the flexural reinforcement effects were very good. And the flexural reinforcement effects depending on the number of anchors and epoxy injection method was confirmed to differ greatly. Additionally, it is possible to predict the required number of anchors to the structure through the strength formula calculation.
