What is Rebar (reinforcement bar in reinforced concrete)?

Steel bars are used in reinforced cement concrete (RCC) to increase the tensile strength cement concrete is also called rebar.

The amount of rebar in typical engineering structures is a small percentage of the amount of concrete. In beams, it is usually about 1% of the cross-section. The rebar in a beam carries the tension forces in bending. In columns up to 6% rebar may be used, partly because the rebar in column also carries some axial forces in addition to tensile forces. When compared to concrete, rebar costs a lot more and hence optimal use of rebar can result in an economical structure.
