The Detailing Of Reinforcement According To CP114: The Structural Use Of Reinforced Concrete In Building

Abstract

Reinforcement should have concrete cover and the thickness of such cover (exclusive of plaster or other decorative finish) should be: 1. for each end of a reinforcing bar, not less than 25 mm nor less than twice the diameter of such bar; 2. for a longitudinal reinforcing bar in a column, not less than 40 mm nor less than the diameter of such bar. In the case of columns with a minimum dimension of 200 mm or under, whose bars do not exceed 12 mm diameter, 25 mm cover may be used; 3. for a longitudinal reinforcing bar in a beam, not less than 25 mm nor less than the diameter of such bar; 4. for tensile, compressive, shear or other reinforcement in a slab, not less than 15 mm nor less than the diameter of such reinforcement; 5. for any other reinforcement not less than 15 mm nor less than the diameter of such reinforcement.
