Abstract

Concrete residues, collected from the outlet of the mixer, are poured into a reception tank, diluted with a controlled addition of water to maintain a constant density, and then pumped vertically into a storage andsettling hopper at 1.5-3 m/sec. to accelerate the settlement of the heavy residual elements. the outlet of this hopper is at a height such that it can be emptied by gravity into the inlet of another lorry/mixer, for transport to a dump. The dilution water flows over the uper wall of the hopper, is filtered through a non-woven synthetic fabric and stored in another tank, and is subsequently used for dilution purposes or for washing the insides of the transporting lorry/mixers. A90% saving in washing water is effected as compared with washing by means of a lance. The cement residues, as rejected, are friable and have lose their mechanical strength on dilution. The treatment device is mobile and can be lifted by a suspending ring.
