Funding paves way for glass in concrete

Waste glass could soon be used as a major ingredient in concrete if a £1.2 million research project finds in favour of the proposal.
WRAP and the University of Sheffield are funding the universitys Centre for Cement and Concrete to carry out two major investigations into the potential for using waste glass in a range of concrete products.
ConGlassCrete I and II are being developed with 25 industrial partners. WRAP is supplying the key funding, £947,000, with a further £140,00 of funding from the university.
Research will focus on developing cullet as a decorative or polished finish in bespoke concrete products and high-value cement-like material to reduce the use of conventional Portland cement. Potential uses include fibre reinforcement and general low-value aggregate for concrete.
ConGlassCrete I would consider uses for mixed container cullet, while ConGlassCrete II would focus on developing market opportunities for the reuse of flat glass, end-of-life vehicle glass, glass fibre and light bulbs, in anticipation of EU legislation.
Both projects will run until March 2004, and have the backing of cement industries, environmental bodies, waste glass producers, collectors and processors and producers of pre-cast and ready-mix concrete.
