Permeable Pavement Systems for effective Management of Strom water Quality and Quantity

Abstract

Pervious concrete blocks, also known as permeable or porous concrete blocks, offer an innovative solution for sustainable urban development by allowing water to pass through their structure, reducing surface flowing water and promoting groundwater recharge. This project focuses on the design, development, and testing of pervious concrete blocks to secure their strength, permeability, and environmental benefits. The study involves selecting appropriate mix proportions of cement, coarse aggregates, and water, while minimizing or eliminating the use of fine aggregates to achieve the desired porosity. Various additives and admixtures, such as fly ash, silica fume, and superplasticizers, are explored to enhance the mechanical and durability properties of the blocks. Experimental tests, including compressive strength, permeability, porosity, and water absorption tests, are conducted to evaluate the performance of the developed blocks. The results are compared with conventional concrete blocks to highlight the advantages and limitations of pervious concrete in different applications. The project aims to contribute to sustainable construction practices by promoting the use of pervious concrete in pavements, sidewalks, and parking lots, reducing urban flooding and mitigating the urban heat island effect. The findings emphasize the potential of pervious concrete as an eco-friendly alternative for modern infrastructure development. Pervious concrete is a special type of concrete with high porosity that allows water to pass through, reducing surface runoff and promoting groundwater recharge. It is an environmentally friendly material used in sustainable construction, particularly in urban areas where storm water management is a major concern. This project aims to develop and analyze pervious concrete blocks for use in sidewalks.
