Twelve column specimens were tested Accepted 19 June 2010 using concrete of compressive strength 24 and 28 MPa mixed with 0.6 and 1 mm tyre rubber particles. For each concrete batch, 27 control specimens were prepared to examine the concrete properties. Using waste tyre rubber-filled concrete leads to a slightly lower compressive strength and modulus of elasticity, Keywords: but the curvature ductility can increase up to 90%. It is concluded that this type of concrete can offer good Rubber-filled concrete
