Concrete Corrosion Inhibitor, MNC-RI Type

MNC-RI type concrete corrosion inhibitor is a mixed-type highly effective inhibitor for reinforcing steel in concrete, suitable for concrete made of ordinary Portland and slag cement. It is mainly applied to the chloride-based corrosive environment, such as marine and coastal engineering, industrial buildings using marine sand with chloride corrosion, etc.

When harmful media such as chloride ion invade concrete, concrete corrosion inhibitor helping form a dense protective film on steel surface can efficiently prevent or delay the electrochemical process of steel corrosion, and then extend the life of steel concrete structure. It features good adaptability to fly ash, slag powder, silica fume and commonly used superplasticizer. When used at above 25℃, our product has the function of obvious early strengthening and procoagulant, and the influence of slump loss.

Dosage of Concrete Corrosion Inhibitor
1. Commonly used dosage is 4% of total amount, while recommended dosage is 4 to 8㎏/m3, which is generally applied in slightly corrosive environment such as industrial and civil buildings and bridges, etc.
2. When used in severe corrosive environment such as harbor engineering, coastal construction and so on, recommended dosage ranges from 8 to 12㎏/m3.

Use Method
1. Firstly, concrete corrosion inhibitor should be dry mixed with dry cement aggregate, stirred well and then mixed with water. Appropriate extra stirring time is needed to ensure the concrete stirred evenly.
2. When our product is composited with other admixture, concrete trial is necessary to ensure its adaptability and air-entraining superplasticizer is not allowed.

Packing
Each bag of concrete corrosion inhibitor weighs 40 kg.

As a professional concrete corrosion inhibitor manufacturer and supplier in China, we also provide flex coat of cement based protective coating, non-dispersible underwater concrete, naphthalene sulfonate formaldehyde condensate concrete admixture, and more.
