Abstract

Abstract

In order to solve the problems of steel bar corrosion and resource shortage, fiber reinforced polymer (FRP) bars with light weight, high strength and corrosion resistance and coral aggregate with similar mechanical properties as common aggregate have become new materials studied by researchers in recent years. In this paper, from the following three aspects: the material characteristics of FRP and coral aggregate as well as mechanical properties of coral aggregate made concrete, the bonding performance and durability between FRP bars and coral aggregate concrete, and the mechanical properties of FRP bars reinforced coral aggregate concrete beams and columns, the relevant research results are summarized. It is considered that FRP bars and coral aggregate concrete have better compatibility and can effectively enhance the performance of coral aggregate concrete structures. In addition, the limitations of FRP bars, coral aggregate and other materials, as well as the shortcomings of the research on the service performance, durability and design method of FRP reinforced coral aggregate concrete members are summarized, which can provide reference for the further research on this new structure.
