Abstract:

A method and apparatus for reclaiming uncured concrete are disclosed. Uncured concrete containing gravel, sand and cement is mixed with water in a concrete hopper and the resultant slurry flows to a screen where the gravel is separated from the rest of the slurry material. The gravel free material flows to a separator where the sand is removed by gravity from the remaining cement water mixture. The cement water mixture flows to a tank where the cement settles out of the water by gravity. Water containing unsettled cement is recirculated to mix it with uncured concrete in the concrete hopper.
