Abstract:
In recent years, rapid urbanization has been experienced in China, leading to numerous environmental damages and resource shortages. To address these issues, the construction of sponge cities has been vigorously promoted. Pervious concrete, as a green building material, is considered an important material in sponge cities. Compared to traditional concrete, its excellent permeability can effectively eliminate surface water accumulation and reduce urban flooding. Additionally, its breathability and noise absorption capabilities are superior to those of traditional concrete. However, the limited mechanical properties of pervious concrete have been identified as a key reason for its restricted application. Consequently, extensive research on its mechanical and permeability properties has been conducted by scholars both domestically and internationally. Research has found that the addition of multiple fibers can improve their mechanical properties while ensuring a certain level of water permeability. Based on this, a review of the impact of different types and amounts of fibers on the performance of pervious concrete has been conducted in this paper.
