Use of waste glass for clinker replacement - Decarbonizing cement industry Innovation Insights - CLIMAX
Waste glass from industries as well as communities is a physical hazard causing damages to humans as well as animals. It also releases toxic pollutants when coming in contact with blood, skin or if it gets contaminated with toxic chemicals. While glass recycling is possible, it has some challenges such as high cost, challenges in recycling broken glass, and challenges with non-recyclable glasses.
Studies suggest that waste glass can be used as partial clinker replacement in the production of cement, finely grinded glass can be used for its pozzolanic properties by producing Portland-cement blends, or filler replacement in cement-based materials as fine or coarse aggregate in mortar or concrete. Use of glass has been found to enhance concrete’s freshness and hardness properties.
