Abstract: This research work presents relationship between cylindrical compressive strength and cubical compressive strength of concrete made with 50% replacement of natural coarse aggregates with recyclable concrete aggregates from old demolished concrete. 200 samples of each cube and cylinder of standard size made using 1:2:4 mix with 0.54 water cement ratio are tested. Based on the obtained results the conversion factor of 0.7 is obtained to convert compressive strength of cube to cylinder. Also, the regression analysis is performed to develop numerical relationship between two strengths. The obtained equation meets statistical norms and successfully predict the compressive strength of cylinders from the compressive strength of cubes.

Keywords: Cube compressive strength, Cylindrical compressive strength, Old concrete, Recyclable coarse aggregates, Fire resistance, Compressive strength, Green concrete.
