Every time you toss an empty jam jar or a cracked drinking glass into the recycling bin, you probably assume it will be melted down into another bottle. But glass can also have a second life in concrete, including pavement and building foundations. A team at Deakin University in Australia tested what happens when waste glass is crushed into fine particles and mixed into concrete instead of sand. The research explored whether recycled glass could partially replace fine aggregate without reducing concrete strength, while also providing another use for waste glass.
A stronger mix than expected
