          Abstract

          Concrete demolition waste can be used as material for manufacturing high quality recycled coarse aggregates, which can replace natural aggregates to make hydraulic concrete mixes. In this study, the behavior of two hydraulic concrete mixes have been analyzed and tested under similar conditions. The comparison of natural concrete with 100% of natural aggregates, versus a specific recycled combination with 30% recycled coarse aggregate and 70% of natural coarse aggregate was studied. Results had shown a similar performance between the two concrete mixes after performing the mechanical tests in the laboratory. The incorporation of recycled aggregates in concrete allowed, in this case a competitive strength class one, which impact in reducing costs when applied in large concrete quantities. This alternative can represent a valuable environmental solution for construction and demolition waste disposal.

          Los escombros de concreto hidráulico representan materia prima para la producción de agregados que pueden ser utilizados en la elaboración de nuevas mezclas de concreto hidráulico. En este trabajo, se estudia el comportamiento de dos tipos de mezclas de concreto hidráulico elaboradas y probadas bajo condiciones similares, en una comparativa entre concretos naturales con un 100% de agregados naturales, y concretos reciclados con 30% de agregados gruesos reciclados y 70% de agregados gruesos naturales. Se observa un desempeño similar entre ambas mezclas al someterse a pruebas mecánicas practicadas en laboratorio. Se concluye que la incorporación de agregados reciclados con estas características específicas, permite concretos de resistencia competitiva de clase uno, que reducen los costos en el uso de concreto masivo y representan una solución ambiental para la disposición final de los residuos de construcción y demolición.
