▎ 摘  要

NOVELTY - Treating waste concrete slurry comprises (i) separating the collected concrete waste slurry from sand and gravel through sedimentation, filtering and screening, recycling the separated sand and stone to the raw material yard for concrete production, and collecting the generated mud water into the waste slurry pool; and (ii) adding clean water into the mud water, adding a slump-preserving blender to the mud water by the waste pulp device, stirring by the stirring system and making finished pulp in the pulp tank. USE - The slurry is useful in concrete (claimed). ADVANTAGE - The concrete slurry effectively reduces the loss of concrete over time, and disperse the cement particles in the waste slurry, absorb the mud particles in the waste slurry, reduces the concentration of the waste slurry, ensures the full and effective use of the waste slurry in the concrete production process, and improves the construction performance of the concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the concrete.
