The Mechanical and Durability Properties of
FRP
Bars‐Reinforced Different Types of Concrete: A Brief Review
Wanru Wang, Jun Dai, Guoqiang Xu, Guanggui Zhang ABSTRACT
Fiber‐reinforced polymer (FRP) composites have been widely applied in various industrial fields, and FRP‐concrete structures have gained increasing recognition in civil engineering. The mechanical and durability properties of FRP and FRP‐concrete structures have a significant impact on the serviceability of the structures. This paper introduces several mechanical and durability properties of FRP. It analyzes the influence of several factors (diameter factor, anchorage length, FRP surface treatment, concrete cover thickness, concrete strength, FRP bar type) on the bond–slip performance of FRP‐concrete, as well as the bonding mechanism between FRP and concrete. Additionally, the paper presents the bonding performance of FRP‐seawater sea‐sand concrete (SWSSC), coral aggregate concrete (CAC), engineered cementitious composite (ECC), ultra‐high performance concrete (UHPC), and recycled aggregate concrete (RAC) structures, as well as the long‐term durability performance of components under different environmental conditions (such as water, high temperature, alkaline solution, etc.). Through the analysis of the above properties of FRP‐concrete components, it is helpful to promote the engineering application of high‐performance FRP‐concrete structures.
