초록

The maximum bond strength of PCS-coated rebar with ultra high-early strength cement and EVA at polymer-cement ratio of 80%, curing ages of 7-day, and coating thickness of 100㎛ is about 1.32 and 1.38 times respectively, the strength of uncoated rebar and epoxy-coated rebar. It is also high bond strength at coating thicknesses of 75㎛ and 100㎛ compared with 150㎛ and 250㎛. It is apparent in this study that the coating thickness is very important factors to improve the bond strength of PCS-coated rebar to cement concrete.
