Jul 01, 2021  This paper presents the feasibility of a novel anchor system that mitigates the end-peeling of carbon fiber-reinforced polymer (CFRP) sheets used for strengthening reinforced concrete beams. Contrary to conventional anchoring methods, CFRP sheets are embedded inside the pre-grooved concrete and covered by a durable polyester-silica composite.
