US: Illinois State University has been awarded a US$15,000 grant by the Environmental Protection Agency (EPA) to research the use of recycled glass as a substitute for Ordinary Portland Cement and fly ash in controlled low-strength material (CLSM). CLSM, also called flowable fill, is a cement-based construction material commonly used for backfilling trenches or other excavations, as well as soil-stabilisation. It can be produced at any ready-mix concrete plant by mixing cement, fly ash, sand and water in the correct proportions.

Project lead Pranshoo Solanki said that preliminary results are promising, and show that required flow and strength can be met by replacing cement and fly ash with recycled glass powder.

The EPA grant is for phase one of the recycled glass project for research at the laboratory scale. Funding for phase two will then be sought to test the product in real-world trials.
