Abstract: Detoriation of environment and depletion of natural resources is a major concern of the hour. Concrete not being an environmental pro material, a lot of work needs to be done on its sustainability parameters. Because of infrastructural growth to cater population needs, huge quantities of concrete are required. Since we all know that aggregates form around 75% of concrete volume, the quantities of aggregate required for the production of such huge quantities of concrete is immense. Hence a sustainable solution for the alternative of aggregate is urgently required to fulfill the shortage of aggregates. Keeping in mind the above problem the present work aims at finding a probable solution for utilizing the recycled aggregate obtained from destruction of hardened concrete. Since literature review suggested the poor performance of the concrete produced from recycled aggregate but did not give the best optimum situation in which it can be used. So the study was carried out on six different mixes containing natural aggregates and recycled aggregate for three different grades of concrete and both fresh and hardened properties of concrete was studied. No admixture was used for making concrete in any of the mixes. The comparative study showed that if recycled coarse aggregate is used with stone dust it gives better result and Total fines if used with natural coarse aggregate gives better result.
