Different types of covering blocks are

1. Wooden cover block.
2. Steel cover block.

Reasons for using Cover Blocks:

1. Maintain a specified distance between the rebar and the shuttering.

3. Provide thermal insulation, which protects the reinforcement bars from fire.
4. Give reinforcing bars sufficient embedding to enable them to be stressed without slipping.
