Abstract

This study presents the results of an experimental study on the cyclic compressive behavior of rubberized concrete under active confinement. Two different mixes of concretes with rubber replacement ratios of 0%, as a control mix, and 18% were prepared. The effects of the incorporation of rubber and the confining pressure on the cyclic compressive behavior of concrete were examined through tests of unconfined and actively confined concrete cylinders. The active confinement was applied by a Hoek cell at different confining pressures, including 5, 10, 15, 20, and 25 MPa. The results indicate that peak stress of concrete decreases, and the peak axial strain and corresponding lateral strain increase by incoporating rubber. The results also show that, at a given confining pressure, concrete exhibits a higher ductility under cyclic loading than that under monotonic loading.
