Most category Gc aggregates can be used as a trench fill drainage stone, as the void space between aggregate particles allow water to flow through. If the rock quarried is resistant to the polishing action of vehicle tyres, aggregate of size 14/20 Gc 85/20, when coated with 1.5% bitumen, is called pre-coated chippings or pre-coats.

increase in aggregate size results in a decrease in the compressive strength of concrete. Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used

Quarry blocks are subdivided by breaking them into smaller blocks that can be removed from the quarry and sent to the mill. Typical mill blocks range in size from 12 to 30 t, but they can reach weights as large as 65 t. Quarry operations thus involve cutting the stone, breaking the stone, and removing the stone from the quarry.
