Why Concrete Cover is very important for Reinforcement bars

Maintaining concrete cover for reinforcement bars of a RCC member is must for quality of construction. Following are the reasons why we should maintain concrete cover for reinforcement bars.

• It protects reinforcement bars from bad effect of weather.
• Concrete cover acts as a thermal insulation of reinforcement bars to protect it from fire.
• It provides enough embedding to reinforcement bars to enable them to be stressed without slipping.
• Protect the reinforcement from this phenomenon called corrosion.
