Development of porous concrete pavements with waste materials for flood control

An inventive design for porous concrete pavement slabs was established in this study. Following the "circularity" agenda and zero waste principles, the design of the permeable concrete mix was founded on several waste/byproduct raw materials, including solidified wastewater treatment sludge (SWS), modified solidified wastewater treatment sludge (MWS), and waste from the desulfurization process (WFDP). Porous concrete was made using cement, waste resources, admixtures, and natural and/or artificial aggregates as component materials. Bulk density, water absorption, compressive and flexural tensile strength, load-bearing capacity, resistance to frost and salt, and abrasion resistance were assessed. Changes in durability and mechanical qualities were tracked as the amount of waste material increased. This study provides a deeper understanding of the properties and possible uses of environmentally modified (green) porous concrete pavement slabs, or pavers, to lower the danger of flooding in urban settings. This concrete is considered environmentally friendly material for sustainable construction because of its porous structure, which significantly assists in regulating stormwater runoff, ensuring infiltration, and reducing the number of pollutants before they reach the groundwater. It has been demonstrated that a specific percentage of recycled materials may be incorporated into porous concrete without compromising the long-term viability or usefulness of permeable concrete, therefore complying with the Zero Waste Agenda and Circular Economy principles.
