The promotion of recycled aggregate concrete (RAC) is an important way for the construction industry to achieve carbon neutrality and sustainable development, but it has problems such as reduced mechanical properties and insufficient bonding performance with reinforcement, which limits its structural applications.
Basalt fiber-reinforced polymer (BFRP) reinforcement has become a high-quality alternative material to traditional steel bars due to its corrosion resistance, lightweight, and high strength.
Fiber addition is a common method to improve the performance of recycled aggregate concrete.
