The relative properties of concrete are of great importance in terms of the serviceability of buildings. The effects of physical and mechanical properties of Recycled aggregate concretes are explained. Here w/c ratio 0.27, 0.30, 0.33 and 0.36 with replacement of 0%, 30%, 35%, 40%, 45% and 50% of Natural aggregates by Recycled aggregates are considered. Taking 3 factors (w/c 4 nos, % Replacement 5 nos and days 3 nos), we arrived at L25 Orthogonal array. To execute this we needed 25 experimental results. Here total 675 specimens were casted (9Cubes, 9Cylinder and 9prism for each trial mixes 25nos).Mechanical properties were found for all the mixes. Attempt is made to compare with different mixes of recycled aggregate concrete. Optimum mix has been proposed.
