Glass Waste Could Replace Sand in Polymer Concrete Mix

New research is making the case for the use of glass waste rather than sand to make stronger and cheaper concrete.

Researchers at Australia's Deakin University are experimenting with a new concrete mixture using various pieces of non-recyclable glass ground up into a coarse powder. That powder is then used as an aggregate in polymer concrete in place of the sand traditionally used. 

Researchers found during testing, the glass-based polymer concrete was significantly stronger than its traditional sand-based counterpart. Additionally, because sand has to be mined, washed and graded, the use of the ground glass could result in lower concrete production costs.
