Concrete recycling Wikipedia

OverviewImportanceProcessUsesPrecautionsExternal links

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete. Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called urbanite.

Concrete change: Making cement carbon-negative Greenbiz

Dec 06, 2018After manufacture, cement undergoes a "carbonation" process wherein concrete exposed to CO2 and humidity slowly bonds with the CO2, storing the carbon in mineral form.
