    Abstract:

    In order to understand the development trend of the research direction of concrete bridge and high-performance materials in 2020, and on the basis of summarizing the research contents, methods and achievements, the follow-up research will be carried out better, this paper reviews the recent literatures from the three aspects of concrete bridges, high-performance concrete materials and high-performance reinforced materials. Furthermore, the literature are classified, summarized and commented. The results show that the current research on concrete bridges pays more attention to durability in the operation stage, working performance in extreme environments, and concrete bridge accidents. For high-performance concrete materials, great progress has been made in the three aspects of high performance, green environmental protection and intelligence. The related high-performance reinforced materials have been mainly focused on the FRP bars with higher strength and better durability. Its application in beams, slabs, columns and other components has been widely studied. Finally, the paper points out shortcomings of the existing research and the work to be done in the future.
