Abstract
Fiber Reinforced Polymer (FRP) composites are widely used in repair and strengthening of reinforced concrete structural elements. The FRP composite adhered to the concrete surface may be separated from the concrete surface in the form of debonding before reaching the ultimate strength. Epoxy resin, concrete strength, fiber properties and application method have an important role in bonding of FRP composites to concrete surfaces. In this study, concrete beam specimens were produced in order to investigate the adhesion of Basalt Fiber Reinforced Polymer (BFRP) composites to the concrete surface using conventional concretes. Stress distribution between concrete and BFRP was investigated by opening a gap in the bottom center of the samples. Unidirectional basalt fiber fabric was used in the production of the test specimens. The effects of concrete surface properties and U winding method on the end of fiber adhesion ability were investigated by bonding BFRP composite to the lower surfaces of the Specimens. Specimens were tested by four point bending experiment. According to the results obtained, the grinding of the concrete surface and the U-winding method significantly improve the adhesion.”
