Abstract
When understanding the influence of concrete surface preparation on the effectiveness of CFRP reinforcement, the load capacity of high-performance, self-compacting, fibre-reinforced concrete (HPSCFRC) is crucial for it efficiency. In this studies, few factors that have an influence on the stress-strain characteristic of concrete confined by CFRP laminates were examined. The method of surface preparation and the number of CFRP layers were considered as crucial parameters that have a significant impact on the characteristics of the load-bearing capacity of reinforced elements. Three different concrete surfaces were examined: grinded, sanded and unprepared. The morphology of each of the concrete surfaces was clearly, and the Abbott-Firestone profile material share curve was then extensively analyzed. During this research, 40 cylindrical concrete specimens were wrapped with one, two and three layers of CFRP, and then subjected to a uniaxial compressive test. The obtained results showed that the morphology of the concrete surface has a real impact on the load-bearing capacity of HPSCFRCreinforced with CFRP. Furthermore, the grinded concrete surface was characterized by the best cooperation with the composite reinforcement.
