Concrete shows weak and strong properties in different cases. The concrete has ability to resist compression forces and has a weak property against tensile forces.
Therefore, we provide reinforcement in concrete to counter the tensile stresses, Because steel has a good properties against tensile forces.
In the Tension zone, we commonly face cracks called (Hair cracks) which was unavoidable in members. In the construction of structures we use many types of the reinforcements having different properties and different diameters ranges from (6 mm to 36 mm) or above in some cases. The selection of steel merely depends upon what type of the forces and loads we are facing.
