The present study carried out for an experimental investigation on both fresh and hardened properties of self-compacting concrete (SCC) containing waste tyre rubber and recycled aggregate (RA). The tyre rubber replaced 5 % and 10 % with coarse aggregate by its weight. The recycled aggregate replaced 5 % and 10 % with coarse aggregate by its weight. Totally 7 mix were prepared including the combination of 5 % tyre rubber with 5 % recycled aggregate and 10 % tyre rubber with 10 % recycled aggregate. The 5 mm and 10 mm size of rubber chips are used. The M30 grade concrete mix design was adopted for the present work. For SCC preparation, the coarse aggregate amount decreased by 35 % and fine aggregate amount increased 35 % with water cement ratio (w/c) 0.43 and super plasticizer (SP) 0.4%. To obtain fresh properties slump flow test, T500 test, J - ring test, V - funnel test, L - box test and U - box test is conducted. For hardened concrete properties the compressive strength, flexural strength and split tensile strength tests are conducted. An attempt has been taken to identify the combine potential effect of tyre rubber and recycled aggregate in concrete and necessity of fresh and hardened properties for the SCC mix.
