The reason behind the usage of reinforcement in concrete
Rebar which is also addressed as reinforcing bar is a key element of reinforced concrete. It is typically structured from ridged carbon steel; the ridges give frictional adhesion to the concrete. Rebar is used for the reason that even though concrete is very tough in compression it is in effect without strength in tension.
One of the most extensively used modern building materials is reinforced concrete. Concrete is defined as an “artificial stone” achieved by mixing cement, sand, and aggregates with water. Fresh concrete can take any kind of shape, giving it an intrinsic benefit over other materials.
The reinforcement in concrete possibly will be simple bar or series of bars, bend to a given schedule which known as bar schedule and tied in accordance with the reinforcement drawings with stirrups.
