Carbon Fiber-Reinforced Polymer (CFRP) strands exhibit superior performance in light weight, high strength, high corrosion resistance, non-magnetic and low linear expansion. In particular, the low risk of corrosion in CFRP strands is promising for long-life span concrete structures. CFRP strands have been primarily used in areas suffering from saline damage due to snow-melting chemicals, coastal areas and also areas with highly acidic soil. However, most CFRP strands have been applied to Prestressed-Concrete (PC) structures as tendons, and there are only a few cases where they have been used in Reinforced-Concrete (RC) structures as a substitute for steel reinforcing bars. Relatively little research has also been carried out on RC structures using CFRP strands. This paper aims to evaluate bond performance of CFRP strands with concrete. In this study, two types of CFRP strand surfaces were embedded in concrete prisms and bond performance was evaluated by measuring tensile strain on the CFRP strands. As a result, the average bond stress was calculated from the transfer length of tensile strain. The distributions of bond stress and the relationship between slip and bond stress were plotted. CFRP strands with surface deformations have better bond performance. This bond stress-slip relationship was fitted to a curve model and represented by an equation.
