Recon Zero is utilized to treat returned concrete leftover from placements turning the returned concrete into dry powder and coarse aggregate that can be utilized as fill material. The technology reduces the need to crush returned concrete resulting in labor and equipment costs. Recon Zero can also be an alternative to investing in concrete reclaiming equipment. Recon Zero has zero impact to the environment and provides an environmentally friendly option to treat returned concrete. Concrete producers can conduct a gradation on the treated fill material, determine uses, possibly sieve out the coarse aggregate for potential blending into other materials. Treated material compacts well for fill material.
