REGENERATED CONCRETE COMPRISING RECLAIMED MATERIAL FROM WASTE CONCRETE AS MAIN MATERIAL, AND METHOD FOR PRODUCING THE SAME, AND METHOD FOR PROCESSING WASTE CONCRETE FOR OBTAINING THE RECLAIMED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide regenerated concrete which has volume not remarkably large compared with waste concrete used as starting raw material, and gives a practical performance in the field of civil engineering and construction by using whole amounts of reclaimed materials (regenerated coarse aggregate, regenerated fine aggregate, by-product fine powder) obtained by processing waste concrete, and a method for producing the same.SOLUTION: The regenerated concrete is produced by using whole amounts of reclaimed materials comprising regenerated coarse aggregate and regenerated fine aggregate obtained by processing waste concrete from demolished concrete, and by-product fine powder generated in obtaining the regenerated fine aggregate, and is characterized in that the by-product fine powder is 10-25 wt.% among the total amounts of the reclaimed materials and the volume of the regenerated concrete is 3.5 or less times the volume of the waste concrete.
