Concrete demolition waste can be used as material for manufacturinghigh quality recycled coarse aggregates, which can replace naturalaggregates to make hydraulic concrete mixes. In this study, the behaviorof two hydraulic concrete mixes have been analyzed and tested undersimilar conditions. The comparison of natural concrete with 100% ofnatural aggregates, versus a specific recycled combination with 30%recycled coarse aggregate and 70% of natural coarse aggregate wasstudied. Results had shown a similar performance between the twoconcrete mixes after performing the mechanical tests in the laboratory.The incorporation of recycled aggregates in concrete allowed, in thiscase a competitive strength class one, which impact in reducing costswhen applied in large concrete quantities. This alternative can representa valuable environmental solution for construction and demolition wastedisposal.
