Durability

Measurement of the depth of corbonation with phenolphthalein

The durability of concrete is traditionally a major issue in the research carried out in the Research Institute of the Cement Industry. The following are some of our key focal points:

  • resistance to carbonation
  • resistance to chloride ingress
  • resistance to freeze-thaw and freeze-thaw with de-icing salts
