CONCRETE COVER BLOCKS

Using Concrete Cover Blocks is adhering to good practices in Construction and provides better bonding with surrounding concrete as it is of same material.
A cover block is a spacer that is used to lift the rebar matrix (jali) off the ground for slabs and similarly for beams and columns a space is created between the shuttering and reinforcements so that concrete may flow underneath and around to become a permanent and integral part of the poured concrete. Prevents rebar from corrosion, Protection during fire for a certain time period.
Cover Blocks should be placed by ensuring that uniform cover is available providing adequate concrete coverage during the pour.
Plastic/PVC Cover Blocks should not be used for the simple reason that it does not bond well with concrete. Plastic has a coefficient of expansion >10 times of concrete and due to temperature variations a gap is formed which ultimately allows a free passage for corrosive agents to reach the steel reinforcements causing it to erode.
Protects the reinforcements from environmental effects to prevent corrosion.
Provides thermal insulation, this protects the reinforcement bars during fire.
Gives reinforcing bars sufficient embedding to enable them to be stressed without slipping.
