Concrete Cover For Reinforced Concrete Structures

Concrete Cover For Reinforced Concrete Structures

The reinforcing bars, surrounded by concrete, do not rust for many decades. This is due to the presence of alkaline medium in the concrete. However, if the reinforcement is not at sufficient distance from the external surface of the concrete structure, air and moisture can be directly accessed to the reinforcement bars, which inevitably leads to its corrosion and destruction.
