Minimum Grade of Reinforced Concrete in Seawater as per IS 456: 2000
In accordance with IS 456: 2000, the minimum grade of reinforced concrete to be used in seawater exposure conditions is M 30.
Explanation
1. Sea Water Exposure
- Seawater is considered a harsh environment for reinforced concrete structures due to the presence of salts and other corrosive elements.
- The chloride ions present in seawater can penetrate the concrete and lead to corrosion of the reinforcement.
2. Importance of Minimum Grade
- The minimum grade requirement ensures that the concrete used in structures exposed to seawater has adequate strength and durability to withstand the corrosive effects of the environment.
- A higher grade such as M 30 provides better resistance to chloride ion penetration and corrosion.
3. M 30 Grade Concrete
- M 30 grade concrete has a minimum characteristic compressive strength of 30 MPa (N/mm2) at 28 days.
- This grade of concrete is suitable for use in marine structures where exposure to seawater is expected.
In conclusion, the minimum grade of reinforced concrete specified in IS 456: 2000 for use in seawater exposure conditions is M 30. This ensures the durability and longevity of structures in such harsh environments.
