Primary Aggregates

Primary Aggregates is a broad term covering all Sands, Gravels, Crushed Stones and certain Slags.

Primary Aggregates are normally from a quarry and have not been used before – the material is in its primary state, just as it was when naturally in the ground.  This differs from Recycled or Secondary Aggregates which have been used, cleaned and sold as an economic and environmentally-friendly alternative.
