Concrete Reinforcing Steel CorrosionInhibitor, RI Type

RI
type concrete reinforcing steel corrosion inhibitor is a mixed-typehighly effective corrosion inhibitor for concrete reinforcing steel. It is usedin concrete composed of ordinary Portlandand slag cement with good adaptability to fly ash, slag powder, silica fume andcommonly used
superplasticizer. Also, it is suitable forchloride-based corrosive environment, such as marine and coastal engineering,industrial buildings with chloride corrosion, etc.

Concrete reinforcing steelcorrosion inhibitor can efficiently inhibit or delay steel corrosion when mixedwith concrete and then extend the life of structure. With the selectivity ofair-entraining agent, it has the obvious early strengthening and procoagulant function andinfluence in slump loss at over 25. Besides, our product can reduce appropriate amount ofwater in the case of maintaining original fluidity.

Usage and Dosage
1. When applied to slightly corrosive environment such as industrial and civilbuildings, bridges and so on, recommended dosage of concrete reinforcing steel corrosion inhibitorranges from 4 to 8/m3. When used in severe corrosive environment such asharbor engineering, coastal construction and so on, recommended dosage is 8 to12/m3.
2. Our product should be added with cement aggregate into the stirring mill fordry mix, stirred well and then mixed with water. Appropriate extra time isneeded to ensure the concrete stirred evenly.
3. When concretereinforcing steel corrosion inhibitor is complexedwith other admixture, concrete trial is needed to ensure its adaptability andair-entraining water reducing agent is not allowed.

Packaging
Concrete reinforcing steel corrosion inhibitor is packed inwoven bag with plastic liner with each bag weighing 40kg.
