Advancements in Pervious Concrete: A Comprehensive Review on Materials, Properties, and Applications

Pervious concrete, characterized by its unique porous structure, has emerged as a sustainable construction material due to its ability to manage stormwater, recharge groundwater, and reduce urban flooding. This review examines the advancements in pervious concrete, focusing on the influence of binders, aggregate types, fiber reinforcements, and admixtures on its mechanical and hydrological properties. Key findings from recent studies highlight the role of mix design in optimizing the balance between compressive strength and permeability. The incorporation of supplementary cementitious materials such as fly ash, silica fume, and geopolymers enhances sustainability while maintaining performance. Aggregate size, shape, and gradation significantly affect porosity, permeability, and structural integrity. Fiber reinforcements, including steel, polypropylene, and carbon fibers, improve tensile strength and abrasion resistance. The use of lightweight and recycled aggregates further emphasizes the material's eco-friendliness. Challenges such as clogging, durability, and standardization of testing methods are also discussed. This paper provides a holistic perspective on pervious concrete's potential to support sustainable urban development and highlights areas for future research, including advanced material innovations and applications in diverse climatic conditions.
