-5mm Concrete Crusher Dust
-5mm Concrete Crusher Dust Demolished concrete is a valuable resource material that can be suitably recycled back into various construction materials. Using recycled concrete in your next construction project eliminates the need for demolished concrete being disposed of at council land fill sites, which assists in protecting the environment from further degradation.

Reclaimed Concrete Material
Reclaimed concrete material (RCM) is sometimes referred to as recycled concrete pavement (RCP), or crushed concrete. It consists of high-quality, well-graded aggregates (usually mineral aggregates), bonded by a hardened cementitious paste. The aggregates comprise approximately 60 to 75 percent of the total volume of concrete.
