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.
Claims15
In a method for the reclamation of unpoured concrete wherein concrete is separated into aggregate, sand and cement slurry fractions, the improvements comprising:
- maintaining said slurry in suspension in a vessel by agitation;
- circulating said slurry in a loop to a point near where concrete mixers are located and back into said vessel;
- and
- periodically opening said loop and supplying said slurry to said mixers as part of the charge to same.
Apparatus for the reclamation and re-use of cement slurries comprising:
- means for separating said slurry from other constituents;
- holding means to contain said slurry;
- agitating means to maintain said slurry in suspension and prevent settling;
- circulating means in the form of a loop adapted to carry said slurry from said holding means to a point near where concrete mixers are located and back into said holding means;
- and
- conduit and valve means in communication with said loop near said mixers adapted to periodically open said loop and supply said slurry to said mixers.
