A Comprehensive Review on the Utilization of Supplementary Materials in Pervious Concrete for Sustainable Infrastructure

The increasing demand for sustainable and cost-effective construction materials has driven research into the incorporation of supplementary materials in pervious concrete. This review paper explores the utilization of waste-derived materials such as fly ash, silica fume, steel slag, and rubber aggregates as partial replacements for cementitious materials and coarse aggregates. The study highlights the effects of these materials on the mechanical, durability, and permeability properties of pervious concrete. Various experimental studies reveal that while the inclusion of rubber aggregates reduces compressive strength, it enhances abrasion resistance and freeze-thaw durability. Similarly, silica fume and fly ash improve strength, reduce chloride penetration, and enhance workability. The impact of porosity, aggregate gradation, and binder content on permeability and mechanical properties is also discussed. The findings indicate that the judicious use of these supplementary materials can lead to environmentally friendly, durable, and cost-efficient pavement solutions. This review serves as a reference for future research aimed at optimizing mix proportions and improving the performance of pervious concrete for sustainable infrastructure applications.
