• Resumen

  • Concrete waste was processed into recycled coarse aggregate (RCA), subsequently used to prepare high-strength (> 50 MPa) recycled concrete. The resulting material was tested for mechanical performance (ULS). The recycled concrete was prepared to the required design strength by adjusting the water/cement ratio. Concrete containing 0, 20, 50, 80 and 100% recycled aggregate was prepared and studied for workability, deformability and durability. The ultimate aim of the study was to prepare high-strength recycled concrete apt for use in cold climates as a theoretical and experimental basis for the deployment of recycled high-strength concrete in civil engineering and building construction.
