Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel,[1] is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has weak tensile strength. Rebar ...
In present investigation, the bond strength of the oil polluted steel bars with concrete was studied. Tests were conducted on 72 cylindrical concrete specimens with compressive strength of 24 MPa at age of 28 days. Two embedded lengths of steel bars were
