A look at the utilization of waste glasses in cement and concrete manufacturing

Due to rising disposal costs and environmental concerns, the use of recycled waste glasses in Portland cement and concrete has piqued attention across the globe. Glass is pozzolanic or even cementitious in nature when finely crushed since it is amorphous and contains comparatively high amounts of silicon and calcium. As a result, it may be used to substitute Portland cement in concrete. The use of broken glasses as aggregates in Portland cement concrete has certain detrimental effects on the concrete's characteristics; nevertheless, practical application may be achieved even with 100% crushed glass as aggregates. The major issue with using crushed glasses as aggregates in Portland cement concrete is the glass aggregates’ expansion and breaking. This article highlights the developments and outlines the guidelines for using waste glasses in Portland cement and concrete properly.
