Waste and Recycled Materials in Concrete Technology ...

Jan 01, 1983  This chapter reviews the waste and recycled materials in concrete technology. Concrete made with Portland cement, water, admixtures, and aggregates comprises in quantity the largest of all man-made materials. Worldwide consumption of concrete amounts to more than 1000 kg per person. The demand is expected to increase in future.

Concrete recycling systems from Liebherr

Concrete pumps cannot discharge residual concrete or cleaning water into the regular truck-mixer hopper because of the low discharge point on the vehicle. Liebherr 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.

Oct 25, 2017  Concrete is, after water, the second most widely used material on the planet. The manufacturing of concrete generates about 4.5 percent of the world’s human-induced carbon dioxide emissions. Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement industry’s global carbon footprint.
