The common name of concrete is plain concrete or called PCC. The concrete is a mixture of
1. Binding material (Cement)
2. Coarse aggregate
3. Fine aggregate
When the concrete was in plastic state (Fresh), we can change it according to our desired shape without compromise its strength. The concrete has a ability to counter or oppose the compression forces but it is weak against tensile forces.
The tensile properties of the concrete can be attained by the additions of other materials such as Steel and Different Steel Mesh, etc. It has good property against the tensile forces, so when the concrete and steel comes together both forces counter properties in concrete was developed (Reinforced cement concrete RCC, Ferro-cement etc.)
