This article aims to study the effect of epoxy resin on bonding strength between rebars and concrete mixed with bagasse ash. The cube specimen, 150 150 150 mm, and 12 mm in diameter of deformed bar were adopted in the pull-out tests to determine bonding between concrete and rebars. Two types of rebar installation, 50 mm deep at the center of cross-sectional area, were investigated i.e., installation during specimen were casting and installation after setting time of concrete by drilling a hole at center of cross-sectional area of specimen then pushed rebar with coated epoxy resin into the hole. In this study, ordinary Portland cement type I was replaced by bagasse ash at 0%, 10%, 20%, 30% and 40% by weight and samples were tested at the age of concrete was 3, 7, 28, 60 and 90 days. The experimental results reveal that at the early age of concrete that mixed with bagasse ash less than 20%, namely 3 and 7 days, the samples using epoxy-coated rebars exhibit higher bonding strength, up to 12%, than the samples without epoxy. However, in the long-term, it is found that bonding strength of the samples using epoxy-coated rebars were gradually increased and the differences in bonding strength are not significance when comparing to the samples without epoxy.
