Why We Make Buildings Of RCC Instead Of Steel?
Though steel has higher compressive strength and tensile strength, due to the following reasons, we can’t build high-rise or skyscraper buildings from steel.
- Steel gets easily corroded, and hence it isn’t weather resistant.
- Compared with concrete, steel is more vulnerable to environmental agencies. So, the durability of steel is more than that of steel.
- Steel is costlier than concrete.
- Steel sections required for the same strength criteria are more slender than concrete, and this gives the feeling of insecurity.
- The strength of steel reduces as the temperature increases. In other words, steel structures are prone to loss of strength with heat.
- Steel is a good conductor of electricity, so, it poses a serious question on the safety of human lives.
