Meta-Analysis of the Performance of Pervious Concrete with Cement and Aggregate Replacements

In recent years, pervious concrete (PC) has gained much attention as one of the strategies for low-impact development (LID) in pavements due to its structural, economic, and road-user benefits. This study sought review evaluate changes mechanical, hydraulic, durability performance PC produced with cement aggregate replacements. A meta-analysis was conducted elucidate feasible range replacement percentage number materials that could be used replace aggregates; single or binary replacements were considered. Results indicated cement-replacing materials, industrial wastes (IWA), recycled aggregates (RA) met minimum requirement properties PC. The use a material provided better than when replaced two more alone used. Industrial waste found RA. combined IWA other most effective method improving Replacements up 40% considered viable replacement, while 50% practical replacement. incorporating different exhibited equivalent improved mechanical maintained hydraulic compared cement-based Nonetheless, limited studies are available on made and/or Thus, coupled applicability acquired from locations need evaluated address viability producing durable
