Abstract - Cover block is one of the basic component on building structure like slab, column, beam, foundation. It is a multi-functionary engineering material. In maximum construction sites, bricks, stones, steel bars are used instead of cover block. This brings a  lots of depraved consequences on building structures like lack of well spacing between surface and reinforcement bars, unbalance position of steel bars, reduce the lifespan of building and  corrosion. Here, the main function of cover block is to reinforce the building structure by avoiding the corrosion on steel bar or avoiding the moisture with the steel bar, providing the resistive property, distributing an uniform  load and  managing  space. In this way,  the  cover  block is  attached  in a reinforcement bar in order to reinforce a building structure. When cover block was applied in a building structure, it made a building   more durable as well as  more attractive by maintaining the shape. This observation suggests that the use of cover block can contribute in strengthening a building structure and maintaining a position and space of a reinforcement bars as well as a structure.

Key Words: Concrete cover block, Reinforcement bar, Potential failure of structure, Space maintaining, Corrosion activity.
