Abstract: Traditional building materials, such as steel, cement, and concrete, have serious problems including large dead weight, low crack resis-tance, poor corrosion resistance, and so on, which leave many unstable factors for the architectural engineering. Compared with that, FRP has specific properties including light weight, high strength, fatigue resistance, corrosion resistance, thermal insulation, sound absorption, non-magnetic and strong designability, which make it attract extensive attention in the engineering field. However, its development as building materials is still in the early stage, especially nowadays it has not been well applied in the new buildings. Therefore, it becomes quite important to study the interdisciplinary integration of materials science and civil science in the respect of FRP. The commonly used reinforced fiber materials in FRP mainly include carbon fiber, aramid fiber, glass fiber and basalt fiber, which are the main contribution of mechanical and chemical properties of FRP, and exhibit excellent performances due to their unique molecular structure and chemical composition. The interfacial bonding strength between the fiber and resin matrix has important effects on the effective exertion of FRP perfor-mance. Fiber modification is generally adopted to improve the surface roughness and surface energy, such as high energy radiation, chemical etching, and surface grafting, which can effectively enhance its mechanical occlusion and chemical bonding with the matrix. In view of the excellent properties, in the field of construction engineering FRP materials are processed into fiber cloth, bars, panels, pipes, grids, cables, anchors, profiles, and other products. Their applications are forced on the existing building reinforcement, and the structural and functional materials for the new buildings. But a lot of exploratory work are still needed in the development of FRP building materials, caused by its anisotropy of mechanical property, low fire resistance, unstable performance, the incomplete engineering standard system, etc.. From the perspective of internal structure and performance characteristics of FRP, the molecular structure and chemical composition of four common reinforced fibers are comprehensively summarized in this paper. And the composite mechanism between the reinforced fiber and resin matrix is analyzed from a microscopic view. The correlation between the macroscopic performance of FRP and its internal structure is established. Meanwhile, the whole and different performance of various FRP materials are analyzed and discussed. Then, the typical FRP products and elements in the field of construction engineering are summarized with examples. The application and research progress of FRP as building materials at home and abroad in recent years are summarized. The main problems existing in the development of FRP and the possible solving measures are put forward. In the end, the development trend of FRP is prospected. Through the systematic combing of structure, property, and application of FRP, the purpose of this work is to offer a reference for realizing high value utilization of FRP in the construction industry.
