The minimum clear cover required for the design of a water tank in severe exposure conditions is 45 mm.
Solution
As per IS 3370, the nominal/clear cover provided to a water tank depends on the exposure conditions. To prevent the reinforcement from corrosion, a layer of concrete should be there in reinforced concrete structures.
Exposure Conditions | Minimum concrete grade | Nominal cover |
Mild | M20 | 20 mm |
Moderate | M25 | 30 mm |
Severe | M30 | 45 mm |
Very severe | M35 | 50 mm |
Hence, the minimum clear cover required for the design of a water tank in severe exposure conditions is 45 mm.
