Crushed Concrete & Concrete Aggregate 101
29.07.2019· What is Crushed Concrete or Concrete Aggregate? Crushed concrete is made up of asphalt debris from other construction projects that can be reused to create driveways, pathways, garden beds and more. When any concrete structure, road, sidewalk or parking lot is demolished, that concrete is usually deposited in a landfill.

Recarbonation - Cembureau
At the end of their working life, reinforced concrete structures can be demolished. If the concrete is then crushed, its exposed surface area increases, also increasing the recarbonation rate. The amount of recarbonation is even greater if stockpiles of crushed concrete are left exposed to the air prior to reuse.

Concrete recycling - Wikipedia
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 ...

Sustainability and Precast Concrete
Precast concrete is also friendly to downcycling, in which building materials are broken down, because it comes apart with a minimum amount of energy and retains its original qualities. An example of downcycling would be the use of crushed precast concrete as aggregate in new concrete or as base materials for roads, sidewalks, or concrete slabs.

At the end of their useful life, buildings and infrastructure (reinforced concrete structures) are demolished.

Reinforced concrete
Concrete is a mixture of coarse (stone or brick chips) and fine (generally sand or crushed stone) aggregates with a paste of binder material (usually Portland cement) and water.When cement is mixed with a small amount of water, it hydrates to form microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid structure. The aggregates used for making concrete should ...
