Abstract

In this study focuses on bond properties of hybrid FRP rebar after chemical environmental exposure. Hybrid FRP rebar bond specimens were subjected to four type of exposure conditions. Bond properties were investigated by direct bond test. Bond test results, hybrid FRP rebars were found to have better bond strength with concrete than currently using GFRP rebar. Also, hybrid FRP rebar had more than about $80\%$ in bond strength of steel rebar.
