Growing concern of the planet due to heavy consumption of sand and coarse aggregate in concrete made it a necessity to find way through sustainable construction practices. Gigantic numbers of building and destruction trashes are produced in emerging countries like India. The clearance of these trashes is serious problem because it requires huge space. Recycled concrete can produce an alternative aggregate for structural concrete as partial or total replacement. The present work is to study the properties of concrete with replacement of 100% of natural sand by manufactured sand and coarse aggregates by different proportions with recycled concrete aggregates (RCA). A mix proportion for M25 grade concrete is derived with standards confirming to IS codes. RCA was partially replaced for coarse aggregate in the proportions of 20%, 40% and 60% fine aggregate by M-sand for 100%. The fresh and hardened properties of thus prepared concrete are studied and compared with concrete made using conventional materials. A comparison with control mix mainly their compressive strength, split tensile strength will allow assessing the suitability of using Recycled aggregate in concrete with replacement to sand with conventional or artificial sand.
