PRODUCT CENTER
RMA reinforced concrete rust inhibitor is a kind of polymer concrete admixture, which has two kinds of powder and liquid, and is directly mixed into concrete or cement mortar in proportion. Because the rust inhibitor contains highly efficient rust inhibitor components, with strong mobility, can penetrate into the depth of concrete, can be adsorbed on the surface of the steel bar to form a layer of molecular chemical protective film, inhibit the cathode and anode corrosion of the steel bar, effectively prevent corrosion caused by various reasons such as chloride, carbonization or stray current, thereby extending the service life of the reinforced concrete structure.
1. Prevent steel corrosion caused by various reasons such as chloride ions, carbonization or stray current.
2. Super penetrating force, can penetrate into the concrete internal protection bar.
3. Strong applicability with cement.
4. Low dosage, high cost performance.
5. Non-toxic and harmless to the environment.
Meet the requirements of JT/T537-2018 (Reinforced concrete rust inhibitor), GB/T33803-2017 "Technical Regulations for the use of Steel Rust inhibitor", JC/T1011-2021 "Concrete Corrosion Preservative", GB/T50476-2019 "Durability Design Standard for Concrete Structure", Specific technical indicators are shown in the following table:

Concrete rust inhibitor has been widely used in submarine tunnels, cross-sea Bridges, Marine engineering, hydraulic engineering, all kinds of industrial and civil buildings, buildings in saline-alkali areas and buildings using sea sand and low alkalinity cement.
When concrete or mortar is mixed, it can be mixed into concrete or cement mortar according to 2 to 4% (weight ratio) of the cementing material content. Concrete or cement mortar should be maintained according to normal maintenance measures without special measures.
1. Liquid plastic ton barrel; Powder is 25kg/ bag;
2. Store in a ventilated and dry place with a shelf life of 6 months.
This product can be added according to different construction requirements, and the mixing time should be appropriately extended when adding. To add this product to the concrete project, the mix ratio experiment must be done in advance.
