IMPORTANCE OF USE OF REINFORCEMENT IN CONCRETE
The importance of reinforcement in concrete can be stated as follows:
1. In RCC ., concrete is very week in tension. steel has very good tensile strength. Therefore steel is used in the tension zone.
2. In columns and beams, steel is used to resist compression and also to confine the concrete.
3. As the temperature coefficient of steel and concrete are nearly equal, temperature stresses are reduced when steel is used in concrete.
4. The concrete shrinks on setting. It provide proper bond between steel and concrete.
5. The modulus of elasticity of steel is very high.
6. Steel is ductile in behavior. More ductility means more elongation of steel before failure. This results in sufficient working time before failure.
7. Steel is also very strong in resisting shear and torsion.
Disadvantage of steel
1. If concrete is porous or if cover to the reinforcement is not sufficient, steel gets rusted and loses strength.
2. Steel loses its strength at high temperature.
