The purpose of this article is to determine the bonding performance between rebar and PVA fiber-reinforced concrete, as well as between superposed members of ordinary concrete and PVA fiber-reinforced concrete. In order to achieve this, specimens of six distinct contact surfaces between PVA-reinforced concrete and regular concrete underwent tensile testing. The findings demonstrate that PVA fiber-reinforced concrete performs significantly better at bonding than regular concrete, and this performance rises with the contact surface's roughness. Additionally, two distinct rebar diameters of PVA fiber-reinforced concrete were created for pull-out testing. The bonding ability of the rebar and concrete was compared to that of regular concrete and rebar. This allowed the author to ascertain the mechanism of failure of the bonding between rebar and PVA fiberreinforced concrete, and to deduce. This experimental investigation that quantifies the impact of polymer fiber on concrete's mechanical characteristics. Regarded as one of the best polymeric fibers for use as concrete reinforcement is polyvinyl alcohol (PVA) fiber. The experimental methods and results for the compressive strength of cubes after 3, 7, 28, 56, and 90 days are presented in this work. The concrete's split tensile and flexural strengths were assessed after 28 days of cure. The concrete known as fiber-reinforced concrete (FRC).
