Hunter Quarries was honoured to host the NSW Rural Fire Service for what was an information sharing and fact-finding mission.
Barmac Manufactured Sand (BMS) is a natural sand alternative often utilised for asphalt and concrete purposes. A coarse sand, BMS is heavily utilised in the production of asphalt, with as much as 45% of each asphalt tonne made up of BMS. It is a product in high demand.
Produced through a Vertical Shaft Impactor (VSI), the quarry rock is graded to produce the appropriately shaped angular particles.
BMS is also preferred by our concrete customers due to its reduced water absorption capacity. For this reason, Hunter Quarries prefers to supply BMS with its improved results in decreasing plastic shrinkage cracking when compared to the CMS alternative.
