DURAHIT® CI25

Corrosion inhibitor for extending corrosion lifetime through increased concrete resistance

Item No. 2917/E

FIELDS OF APPLICATION

DURAHIT® CI25 is a corrosion inhibiting admixture designed to avoid corrosion of reinforced and prestressed concrete.
Corrosion is the major structural threat to concrete constructions. DURAHIT® CI25 improves the durability of reinforced concrete at the level of the concrete and the rebar:
▪ DURAHIT® CI25-based admixtures provide corrosion inhibition for reinforcements. Forming protective hydroxide layers around the reinforcements and enhancing chloride fixation promotes rebar durability
▪ DURAHIT® CI25-based admixtures increase strength and reduces porosity of the concrete itself, which leads to an improved resistance towards water and chlorides migration as well as against mechanical stress.

WORKING PRINCIPLE

Nitrate in DURAHIT® CI25 reacts with iron to form hydroxide layers. Those layers prevent corrosion of steel reinforcements. The protective effect of DURAHIT® CI25 is comparable to that of nitrite, which has been used successfully for many years.
DURAHIT® CI25 is the environmentally friendly alternative to nitrite.
