Concrete Reinforcing Steel Corrosion Inhibitor, RI Type

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

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


Specifications
Items Specification
Air content (%) ≤ 4
Bleeding rate ratio (%) ≤ 100
Time interval between initial and final set (min) -90~+120
Compressive strength (%) ≥ 100
28 day shrinkage rate (%) ≤135

Usage and Dosage
1. When applied to slightly corrosive environment such as industrial and civil buildings, bridges and so on, recommended dosage of concrete reinforcing steel corrosion inhibitor ranges from 4 to 8㎏/m3. When used in severe corrosive environment such as harbor engineering, coastal construction and so on, recommended dosage is 8 to 12㎏/m3.
2. Our product should be added with cement aggregate into the stirring mill for dry mix, stirred well and then mixed with water. Appropriate extra time is needed to ensure the concrete stirred evenly.
3. When concrete reinforcing steel corrosion inhibitor is complexed with other admixture, concrete trial is needed to ensure its adaptability and air-entraining water reducing agent is not allowed.

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

As an experienced concrete reinforcing steel corrosion inhibitor manufacturer in China, our company offers a vast range of products that includes epoxy repair mortar, concrete fiber, amino acrylsulphonate phenol formaldehyde condensate concrete admixture, high strength non-shrink grout, and much more.

  • PCL Polycarboxylate Superplasticizer Concrete AdmixturePCL polycarboxylate superplasticizer concrete admixture features good stability especially at low temperature. Besides, the liquid concentration of our product can be diluted from 50% to 10% and then you can directly use the diluted product as pumping admixture of mixing plant.
  • FDN Naphthalene Sulfonate Formaldehyde Condensate Concrete AdmixtureCompared with UNF-5 type, FDN naphthalene sulfonate formaldehyde condensate concrete admixture has higher water reducing rate and fewer concrete slump loss, which can efficiently increase the concrete fluidity, reduce bleeding and segregation and then improve the workability of concrete.
