What is Clear Cover in RCC Member - Clear Cover in different RCC Structure
Clear Cover is the distance between the outer surface of a concrete member and the nearest edge of the reinforcing steel. It acts as a protective barrier to shield the rebar from corrosion, moisture, and fire damage, ensuring the structure's longevity. Standard values vary by member, such as 20 mm for slabs, 25 mm for beams, 40 mm for columns, and 50 mm for footings. Maintaining this gap is essential for creating a strong bond between the steel and concrete.
