The Behavior of Bond Strength between Rebar and Concrete in Rubberized Concrete

Through an experimental program of eighteen specimens presented in this paper, the bond strength between reinforcing bar and rubberized concrete was produced by adding waste tire rubber instead natural aggregate. The fine coarse aggregate replaced 0%, 25%, 50% with small pieces a tire. Natural replacement ratio, rebar size, embedded length, yield stress rebar, cover, compressive were studied investigation. Ultimate stress, stress-slip response, failure modes presented. results reported that reduction 19% noticed compared conventional concrete. increased when concrete, increased. Meanwhile, length size decreases strength. push-out splitting observed
