Abstract

Impermeable structures have replaced the original natural permeable structure, leading to frequent occurrences of urban runoff, flooding, and heat island effects. To address these issues, a new type of material that can function as a sponge city has been proposed - pervious concrete (PC). However, the performance of PC must be improved significantly. One potential solution is to incorporate fibers into the mixture, similar to those used in conventional concrete. This review aims to identify the optimal manufacturing methods, analyze the effectiveness of different fiber types, and determine the recommended dosage of fibers for improving PC's performance. The review focuses on fiber-reinforced pervious concrete (FPC), examining the current state of knowledge regarding mix design, mixing procedures, compaction techniques, and curing methods for fiber integration. By analyzing the available experimental data from published studies, recommendations are made for optimizing fiber usage in PC, including selecting suitable fiber types, lengths, aspect ratios, and volume fractions. Additionally, the latest findings from five distinct fiber types are summarized across five properties: compressive strength, flexural strength, splitting tensile strength, porosity, and permeability. Finally, potential research gaps are identified to guide future investigations.
