Powdered Corrosion Inhibitor & Waterproof Admixture for Reinforced Concrete

If the membrane-free powdered corrosion inhibitor and waterproof admixture is added when making concert, it will improve waterproofness of concrete by three times and, at the same time, increase the rate of rust resistance of iron reinforcing rods by more than 95 %; therefore, without additional membrane-type waterproofing works, the waterproofness preventing the penetration of water and moisture and the rust resistance protecting iron rods from being corroded due to chemically deteriorating substances can be sustained for the same duration of the concrete, from which the longevity and durability of a structure can be expected.

It is a powder-type corrosion inhibitor and waterproof admixture for reinforced concrete that produces high quality structures with high durability by providing rust resistance to reinforcing iron rods, where structures are placed to block water or moisture, or where the coating thickness of concrete is very thin or where cracks on the surface of concrete generated from the behavior or vibration of a structure allow for the penetration of harmful ions.

Features

The membrane-free powdered corrosion inhibitor and waterproof admixture, an artificial inorganic composition, is designed to improve the waterproofness, anticorrosion, and durability of concrete itself through chemical reactions of such compounds as Pozzolan activator, siliceous powder, stearates, and dispersible polymer powder and thus lengthen the life of structures. In addition, it is also an environment-friendly new material that can ensure the uniform quality of concrete when mixing it in a batcher plant or a truck agitator by making component materials lighter and maximizing their dispersibility. It is more advanced than membrane-type waterproofing admixtures and has following characteristics.

• Simple construction method and easy quality control are ensured by means of process rationalization

• Constructability and compatibility with other chemical admixtures for concrete are excellent

• It has an excellent resistance to chemicals, rust, freezing and thawing, and abrasion

• Additional work for corrosion inhibition is not necessary thanks to inherent antirust and waterproof abilities

• Longer duration of structures reduces waste materials, which is eco-friendly

Application

• Concrete structures in offshore and coastal areas

• Waste water treatment plants

• Tunnels and subways

•. Waterproofing of concrete bridge decks in areas where corrosion to rods proceeds fast.

• Precast concrete products that require anticorrosion and waterproofness
