Mapei SpA, Via Cafiero 22, 20158 Mailand, Italy


Returned concrete is the unused ready-mixed concrete that comes back to the plant in the concrete truck as excess material. Typically, the amount of waste concrete generated by ready-mixed deliveries can be as low as 0.4% to 0.5% of total production. However, during peak periods, when pressure for supply is greatest, the waste can increase to 5% to 9%.

These data confirm that returned concrete is a heavy burden for the ready-mixed plants and sums to the other C&DW.
