The minimum thickness of reinforced concrete cover 1. The environmental category of indoor parts below the ground and concrete structures above the ground is Class I; The environmental category of the concrete structure below the ground at the side contacting the water and soil is Class 2a, and the minimum thickness of the concrete protective layer of the outermost reinforcement shall meet the requirements of the following table, except as noted in the figure: environmental category: slab, wall, shell beam, column, pole foundation note: 15mm 20mm 50mm 1. When the concrete strength is not greater than C25, the value in the table shall be increased by 5mm. 2. The thickness of concrete cover shall not be less than the diameter of longitudinal reinforcement. II a 20mm 25mm II b 25mm 35mm 2. The thickness of concrete cover for embedded pipes in beams and slabs shall not be less than 30mm. 3. Plain concrete cushion blocks not lower than the strength grade of corresponding concrete components can be used in each component to control the thickness of main reinforcement protective layer.
