▎ 摘　　要

NOVELTY - Wave-absorbing regenerated concrete comprises 100-150 pts. wt. copper slag powder, 700-900 pts. wt. fine aggregate, 290-420 pts. wt. cement, 110-840 pts. wt. modified regenerated aggregate, 360-990 pts. wt. natural coarse aggregate and 180-200 pts. wt. water. The modified regenerated aggregate is obtained by modifying the regenerated aggregate with graphene oxide/polyvinyl alcohol/polyacrylamide nano composite hydrogel. USE - Used as wave-absorbing regenerated concrete. ADVANTAGE - The wave-absorbing regenerative concrete has good wave absorbing performance on the basis of the service condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of wave-absorbing regenerative concrete.
