• 'Aggregate' is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.

glass aggregate begins as post-consumer recycled glass. Glass of all colors is cleaned to <1% non-glass to eliminate contaminants that may alter the consistency of the finished product. The cleaned glass is milled into a superfine powder, which is measured and mixed with a ing agent prior to being kiln-fired.
