NOVELTY - The method involves crushing the waste concrete block, crushing the concrete block into multiple crushed stones, removing the reinforcing steel bar, large wood and plastic, sieving, crushing, placing the crushed stone sieved in different clean water tank, stirring, filtering the suspended substance floating on the water surface, taking the crushed stone out and drying, placing the cleaned macadam in acidic tank, taking out the acidic solution on the surface of the cleaned macadam, placing in alkaline pool, taking out the alkaline solution on the surface of the cleaned macadam, cleaning the dust and the redundant solution, soaking the crushed stone in the concrete reinforcing agent, grinding the crushed stone to obtain clean crushed, grinding and sieving to obtain grinding regenerated fine aggregate, performing superfine grinding treatment to the crushed stone to obtain regenerated milled and mixed material, mixing crushed stone with sand for stirring, grinding, drying and collecting. USE - The method is useful for regenerating green concrete. ADVANTAGE - The method removes the reinforcing steel bar, large wood and plastic, and the impurity in the gravel, ensures the pure degree of the regenerated concrete, and the strength of the regenerateated concrete, allows secondary utilization of mud and waste gas concrete generated when preparing regenerated cement, and improves the utilization rate of the resource.
