recycle of material by concrete technology

Concrete recycling systems from

Concrete pumps cannot discharge residual concrete or cleaning water into the regular truck-mixer hopper because of the low discharge point on the vehicle. therefore supplies a low-level loading hopper with conveyor. Material can then be discharged by the concrete pump and transferred to the recycling plant without diffi culty.

Concrete recycling creates bendy new construction material

The researchers adjusted the mixture proportion, pressure, temperature, pressing duration, and water content of the material; finding the right proportion of concrete and recycled wood was critical to obtaining concrete with the most strength. Wood gets its rigidity from lignin, which are highly crosslinked organic polymers.

Sustainability - U.S. Concrete

CO 2 emission – The use of recycled materials in concrete reduces greenhouse gasses, frees up landfill space, and reduces raw material consumption. Recyclable – After a concrete structure has served its original purpose, the concrete can be crushed and recycled into aggregate for use in new concrete or as a backfill or road base.
