Why are the rods are required to have some concrete coverage?
Expert Solution
Step 1
The space between the reinforcing rods and the concrete is called as concrete cover. While pouring the concrete mix in the form work, the reinforcing rods will move from the fixed position. So the concrete blocks are used to maintain the space for the concrete cover.
The reinforcing rods are required to have concrete cover because
- To prevent the rods from corrosion.
- To increase the durability the rods by providing thermal insulation.
- It is used to provide adequate embedding of rods without slipping.
The concrete cover is based on the structural member. The minimum thickness for various structural members is
