About Concrete cover block.

Concrete  cover block is basically a spacer that is used to lift the rebar matrix off the ground so that concrete may flow below the rebar. In order to prevent corrosion of the rebar, it has to be totally sheathed in concrete. It usually needs about 2 to 3 inches of coverage on all sides.
Concrete cover block for reinforcement is required to protect the rebar against corrosion and to provide resistance against fire. The thickness of cover depends on environmental conditions and type of structural member.


Advantages of Cover Block Blocks

Concrete Spacers prevent rebars from corrosion, protect them from fire to certain length of time and help to provide proper transfer of stresses from concrete to steel rebars, by helping provide proper cover to rebars.
a) Protection of the Rebar from the environment by providing a physical barrier.
b) It provides thermal insulation, which protects the reinforcement bars from fire.
c) To give reinforcing bars sufficient embedding to enable them to be stressed without slipping.
d) Ensures that concrete completely encircles Rebar allowing passivation.
e) Ensures that concrete completely encircles Rebar allowing complete bond to develop. Allows the Rebar to assume position and act as designed.
f) Prevents staining.
g) Provides a time lag in case of fire.
