CHRYSO®CI 2005 is based on Calcium Nitrite, which interacts with the structural steel in concrete to prevent chloride attack.

CHRYSO®CI 2005 chemically reacts with steel to maintain a passivating layer when chlorides penetrate the concrete, significantly delaying the rate of corrosion.

  • CHRYSO® CI 2005 increases life of all reinforced concrete structures.
  • CHRYSO® CI 2005 chemically inhibits the corrosive action of chlorides on all reinforcing steel and pre-stressing tendons.
  • Can be used in conjunction with other admixtures, but should be added to the mix separately and must not be mixed together prior to addition.
  • CHRYSO® CI 2005 is a Water based & non-flammable, therefore safe to use.
  • Offers Owners, Clients, Engineers and Govt. Bodies, a timeproven, corrosion inhibiting technology that will extend life of all reinforced concrete structures.
Domains of application

When used in fresh concrete mixes, CHRYSO® CI 2005 will seek out and form a corrosion inhibiting protective layer on metals. Project specifications will determine addition rates, which should be pre-determined following projected chloride ion ingress over the life span of the structure. Preliminary tests should always be carried out to determine the effects on the concrete mix design.
