Influence of Aggregate Characteristics and Durability Aspects on the Performance of Pervious Concrete: A Review

Pervious concrete is a sustainable construction material known for its high porosity, making it effective for stormwater management and groundwater recharge. The performance of pervious concrete is influenced by aggregate characteristics, including size, shape, and type, as well as the mix design and curing conditions. Research indicates that aggregates with higher angularity improve permeability, while finer aggregates enhance strength by reducing void content. The incorporation of recycled aggregates, silica fume, and supplementary cementitious materials has been explored to optimize mechanical and durability properties. Durability remains a critical concern in pervious concrete applications, particularly in regions with freeze-thaw cycles. Studies suggest that latex modifiers, air-entraining agents, and the inclusion of fly ash improve resistance to abrasion and environmental stressors. Additionally, the use of smaller aggregates has been shown to enhance abrasion resistance. Despite these advancements, achieving an optimal balance between strength, permeability, and durability remains a challenge. This review summarizes recent findings on the effects of aggregate characteristics and durability-enhancing materials, providing insights for the development of high-performance pervious concrete.
