Abstract

A process for producing a coated aggregate for construction concrete, in which the coating consists of cements, concrete additives and/or additional substances, as well as other auxiliary substances, is characterised in that a compact and dense coating which is thinner than the grain diameter is applied on the grain surface of the round or broken aggregate. The coating is applied by progressive agglomeration. For this purpose, the aggregates are previously wetted, the coating being formed by cement which is uniformly added at the same time as water is sprayed. A light aggregate with an open-pore structure sealed by the coating is used, providing a light construction concrete which has in the form of fresh concrete a constant processability and pumpability. The thus obtained concrete has predictable apparent densities in the fresh and set state, as well as a defined concrete solidity.
