A Review of Research on Basalt Fiber Reinforced Polymer Self-Compacting Concrete Columns

Abstract

As a new type of high-performance concrete, self-compacting concrete (SCC) has been widely used in modern construction projects due to its excellent working performance, construction convenience and good durability. However, compared with common concrete (NC), the elastic modulus of SCC is relatively low, which limits its application in terms of bearing capacity and deformation performance to a certain extent. As a new type of environmentally friendly reinforcement material, basalt fiber reinforced polymer (BFRP) has shown great application potential in the field of concrete structure reinforcement due to its excellent mechanical properties, good corrosion resistance, abundant raw material sources and environmental friendliness. This paper systematically reviews the current research status of BFRP-reinforced SCC columns, focusing on the differences in material properties between SCC and NC, the performance comparison between BFRP and other fiber-reinforced polymer materials, the main reinforcement methods of concrete columns, the experimental research progress of BFRP-reinforced concrete columns, and the current status of numerical simulation research. Through an in-depth analysis of existing research results, the main problems existing in current research are identified, especially the blank areas of BFRP-reinforced SCC columns. Based on these analyses, this paper proposes the key directions for future research, which will provide an important reference for promoting the theoretical research and engineering practice of BFRP-reinforced SCC columns.
