Waste Glass in Concrete Shows No Decay After 3 Years
Engineers replaced 20% of the cement in a field project with powdered waste glass. Three years later, the concrete showed no deterioration or material failure. Recent studies suggest this mix can raise compressive strength and lower water absorption. Cement production is widely described as a major contributor to environmental harm.
Context
Context: Cement is one of the most widely used building materials, and making it releases large amounts of carbon dioxide. Glass waste is common and often ends up in landfill, so reusing it in construction helps cut both waste and emissions.
