The paper undertakes the compressive strength test on the concrete specimen by mixing the mineral powder, the fly ash, and the min- eral powder and fly ash( 1 : 1 ) whose the double mixing are respectively 10% , 20% and 30%, and replacement ratio of regenerated coarse aggre- gate is 60%, adopts the supersonic rebound method to test its compressive strength, points out the strength-measuring regression equation, and the research development of the nondestruction test of the regenerated concrete.
