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.
