Hunter Quarries engaged in a mammoth task of gaining extension of hours to crush and supplying Class 2 Armour Rock to Central Coast Council to protect coastal erosion.
Manufactured sands are a by-product of the quarrying process with different quarrying processes affecting the shape and gradings of the materials.
When used in concrete, manufactured sands often provide increased bonding strength compared to natural sands. Due to the effects of long-term weathering and erosion, natural sands are made up of far more rounded particles, which adversely affects its bonding properties.
Additionally, the increased use of manufactured sands minimises the mass relocation of natural sand deposits, reducing the impacts on these often delicate pockets of our environment.
At Hunter Quarries, we’re able to provide three manufactured sand alternatives, Barmac Manufactured Sand (BMC), Barmac Cone Combination Manufactured Sand (BcCMS) and Cone Manufactured Sand (CMS).
