Sustainable production of concrete containing discarded beverage glass as fine aggregate

Discarding of waste glass is creating major ecological issues across the globe. In recent years, the rate of disposal of this material has amplified. One conceivable approach is to employ this rejected material as a substitute of fine aggregate in concrete. Hence, this study examines the behaviour of concrete with waste glass as fine aggregate at various substitution levels (18%, 19%, 20%, 21%, 22%, 23% & 24%). Fresh, hardened and durability properties were evaluated in terms of workability, compressive strength, flexural strength, density and water absorption. The outcome of the present work indicates that inclusion of waste glass has led to the enhancement in quality of microstructure up to 21% substitution of fine aggregate. This has improved the mechanical properties of such concrete mixes. It is observed that water absorption and water permeability are negatively affected with increment of waste glass in concrete. Hence, it can be concluded that 21% of fine aggregate can be replaced by waste glass to manufacture concrete for non-aggressive environment.
