Description
Cover blocks are small blocks made of concrete or plastic that are used to maintain the distance between the reinforcement bars and the formwork in reinforced concrete structures such as columns, beams, and slabs. The purpose of cover blocks is to ensure that the reinforcement bars are located at the correct distance from the surface of the concrete, which helps to prevent corrosion and ensures that the structure is strong and durable.
