The work aims to facilitate 100% recycling of waste concrete as aggregates and fines. There are three phases in this study (i) development of the waste recycling process, (ii) performance evaluation of recycled aggregates in concrete, and (iii) use of direct concentrated solar radiation for beneficiating the recycled aggregates, which is an extension of the first phase of the study. This presentation will focus on the effect of incorporating thermo-mechanically beneficiated recycled concrete aggregate (RCA) on the mechanical and durability properties of concrete. Concrete was prepared by substituting pristine granite aggregate and river sand with coarse and fine RCA at different replacement levels. The mechanical properties of recycled aggregate concrete (RAC) were found comparable to the reference concrete, with some reduction of performance at high replacement ratios; these results along with durability tests show that beneficiated RCA could replace pristine aggregate completely and can be used for structural grade concrete. Finally, the presentation will summarise thermo-mechanical beneficiation process with direct concentrated solar radiation replacing the electric furnace heating. The use of solar energy would make this process environmentally friendly and economically feasible, and lead to energy savings of up to 250kWh per tonne of waste concrete.
