CONCRETE COVER BLOCK
WHAT ARE COVER BLOCKS?
A cover block is essentially a spacer that is used to lift the rebar matrix off the ground so that concrete may flow underneath the rebar. To prevent corrosion of the rebar, provide better reinforcement a fire resistance to the rebar. It needs to be fully encased in concrete. It usually needs about 2 to 3 inches of coverage on all sides.
Types Of Cover Block
Concrete Cover Blocks/ PVC (Plastic) Cover Blocks
Why Do We Need to Maintain Clear Cover?
- To protect the steel reinforcement bar (rebar) from environmental effects to prevent their corrosion.
- To provide thermal insulation, which protects the rebar from fire.
- To give rebar sufficient embedding to enable them to be stressed without slipping.
Difference between a Construction Mart Cover Block & Site Made Cover Block?
Site made cover block :
- Not uniform in size, shape & thickness.
- Possibility to displacement at the time of concreting for irregular size, shape & thickness.
- Site-made mortar blocks are usually porous.
- Site-made mortar blocks are not the same quality as concrete.
- Naturally, site made cover block does not comply with the technical requirements.
- Site-made cover block. If we don’t provide the proper clear cover, rebar will corrode with time and will ultimately result in premature failure of the structure…
Construction Mart Cover Blocks :
- CM Cover Blocks are manufactured under precision M40 to M60 Grade concrete mixture.
- CM Cover Block Clear cover maintains 100% Compressive strength more than the surrounding concrete.
- CM cover block is a multi-dimensional cover block that is used to ensure the perfect clear cover to rebar in the concrete structure.
- Cast in precision mold to ensure the accurate dimension.
- Made of high-quality concrete elements.
- Water absorption is less than surrounding concrete.
- Shape Uniformed.
- Have a uniform grip to bear rebar, which protects rebar from displacement while concreting.
- Create bond area better
- Well cured
- Labor cost savings due to rapid and simple rebar laying operation.
- Cost effective.
- No wastage.
- Ready to use.
