Abstract: A no-discharge concrete reclamation system that eliminates all waste products and associated pollution. In addition to separating and washing sand and aggregate as provided in conventional systems, the invention provides for holding the water-cement slurry in suspension while continuously circulating same with a transfer pump to a point near the batching plant. On demand, slurry for batching from the circulating stream is provided to the mixers. Preferably, clarified wash water is held separately and used to provide mixer wash water, and/or make-up water for the slurry.
