Potential use of crushed waste glass and glass powder in sustainable pervious concrete: A review

Abstract

This review explores the innovative use of crushed waste glass and glass powder in sustainable pervious concrete, emphasizing their potential to enhance mechanical properties and environmental benefits. Pervious concrete, characterized by its high porosity and permeability, is crucial in stormwater management and reducing urban heat. However, its inherent low compressive strength necessitates the incorporation of supplementary materials. This study highlights the pozzolanic activity of glass powder, which improves strength and durability while reducing the overall cement content, thereby lowering the carbon footprint associated with concrete production. The review addresses the challenges of using high glass powder replacement levels, including potential compressive strength reductions and increased susceptibility to freeze-thaw cycles. Future research directions include optimizing mix designs and investigating hybrid approaches that combine glass powder with recycled aggregates. Ultimately, this review underscores the vital role of waste glass in promoting sustainable construction practices and contributing to the circular economy within the pervious concrete industry.
