PERFORMANCE WITH GLASS AS POZZ./AGG.PRODUCTSTYPE


ConclusionsGlass as both pozzolan and aggregate performed adequately in ready-mixed concrete and a range of precast concrete products tested to relevant British Standards;No ASR expansion was observed in glass pozzolan and/or glass aggregate ready-mixed concrete and precast concrete products, except in one example where high alkali cement was used.Ready-mixed concrete made with glass pozzolan and/or glass pozzolan and glass sand shows increasing strength development to 1 year
