CPO 40

Most important physical characteristics

In cement tests

• Minimum Resistance at 28 days 40 N/mm² (408 kg/cm²)
• Setting times
  Initial: 45 minutes (minimum)
  Final: 600 minutes (maximum)
• Volume stability in autoclave
  Maximum expansion 0.8%
  Maximum shrinkage 0.20%

Most important chemical characteristic

• Maximum sulfur trioxide 4.0%
• Maximum loss on ignition 5%
• Maximum insoluble residues 5%

The CPO 40 cement is ideal for building structural elements in general and any kind of work.

This cements gives a high early resistance to concretes.

Recommended for transformers and concretes for the rapid reaction of its components.

In case of contact with eyes, rinse with plenty of water.

Use

• Use appropriate sand, gravel, and water.
• Mix with the least amount of water possible to obtain the desired slump.
• Use the best mixing method for obtaining a uniform concrete.
• Place and compact the concrete as best as possible.
• Cure for at least 7 days keeping the surface of the concrete moist and protected from extreme temperatures.

Handling bulk cement

• Store the cement in silos, making sure they are covered and that there are no residues of other products.
• If it is not stored in silos, keep the cement protected from humidity, place it in clean surfaces or containers.

BIG BAG

With a weight from 1.5 to 2 tons, it is ideal for transformers that use it for pre-manufactured elements; as well as works requiring rapid resistance.

Special equipment for its handling is required, such as forklifts or if applicable loader backhoes or hiab with enough capacity.
