Project Based Learning: Development of Pervious Concrete Paver Blocks for Buildings and Roads

              This review provides a comprehensive overview of the development and application of pervious concrete paver blocks, emphasizing their role in advancing sustainable construction practices for both buildings and roadways. Pervious concrete, renowned for its high porosity, facilitates effective storm water management by allowing water to permeate through the surface, thus mitigating runoff, reducing heat island effects, and enhancing groundwater recharge. The review details innovations in material composition, including adjustments to aggregate size, binder types, and the incorporation of supplementary cementitious materials (SCMs) such as fly ash and slag, which have significantly improved the durability and load bearing capacity of pervious concrete. Despite its generally lower compressive strength compared to traditional concrete, advancements in mix design and reinforcement techniques, such as the use of polymer fibers and improved curing methods, have enhanced its mechanical properties and structural performance. The review also explores the challenges related to the long-term durability of pervious concrete paver blocks, such as issues with clogging, freeze thaw resistance, and abrasion, and discusses recent developments in surface treatments and maintenance strategies aimed at addressing these concerns. The practical applications of pervious concrete paver blocks include their use in parking lots, walkways, and roadways, where they offer not only environmental benefits but also aesthetic flexibility and improved safety. Future research is needed to further optimize mix designs for increased durability, explore innovative reinforcement methods, and evaluate the long-term performance of these paver blocks in various climatic conditions. By addressing these areas, the review provides valuable insights into the ongoing evolution of pervious concrete technology and its potential to contribute to more sustainable and resilient infrastructure.
