When demolished concrete waste aggregates were used instead of new aggregates, the water absorption went up from 1.58 to 4.65%. This shows that the water-cement ratio got better. The crushing value went up from 26.54 to 55.29%, the impact value went up from 27.86 to 58.05%, and the abrasion value went up from 26.96 to 35.58%.Web
