(57) A method and apparatus for producing liquified Alternative Supplemental Cementitious Material (ASCM) from an uncured concrete slurry. Uncured concrete slurry is received into a receiving hopper, diluted with water, and pumped upward through a slurry discharge conduit to an aggregate separator that screens the gravel and sand for separate discharge. The remaining ASCM entrained water flows into a holding tank. The ASCM settles to the lower portion of the holding tank. The holding tank stores the remaining water for re-use diluting uncured concrete slurry. The ASCM is liquified and moved towards the ASCM discharge port by an agitator system located in the bottom of the holding tank. From the discharge, a pump delivers the liquified ASCM through a conduit for discharge. The discharged ASCM can be used as a partial replacement for Ordinary Portland Cement and as an ingredient in flowable fills.
