Offshore anti-chloride corrosion inhibitor concrete corrosion inhibitor

Corrosion has caused significant damage to many concrete structures, severely impairing the usability of buildings, reducing their service life, and substantially increasing maintenance and repair costs. Groundwater contains harmful impurities such as sulfates, magnesium, and chloride ions, which interact to primarily form three types of erosion on mortar and concrete: E-salt erosion forming ettringite, G-salt erosion forming gypsum dihydrate, and M-salt erosion where Mg²+ decomposes cement hydration products. The use of concrete anti-corrosion agents can improve construction efficiency, prevent and reduce the hazards of corrosion, and is widely applicable in adverse geological areas and marine environments such as saline soil regions, salt lakes, coastal salt pans, port areas, and seawater intrusion zones across the country.

I. Product Features

By adding concrete anti-corrosion agents, the concentration of SO₂⁻ ions invading the concrete can be effectively reduced, and the capillary pore size can be refined, inhibiting expansion damage and delaying the rate of sulfate erosion damage to concrete, thereby enhancing its durability.

◆ Highly effective in preventing concrete corrosion damage, with some improvement in early strength of concrete.

◆ Increases the density of concrete, improves its impermeability grade ◆ Enhances the concrete's ability to resist corrosion damage caused by magnesium ions ◆ Improves the frost resistance of concrete

II. Performance Indicators

III. Application Scope

◆ Industrial and civil construction projects frequently exposed to corrosive media ◆ Industrial and civil construction projects in saline-alkali areas prone to corrosive media erosion.

◆ Used for the construction of underground pipelines, embedded metal components, and the repair and reinforcement of reinforced concrete structures already damaged by corrosion.

◆ Structures subjected to sulfate erosion.

IV. Construction Process

◆ This product can be added according to different construction requirements, and the mixing time of concrete should be appropriately extended during addition.

◆ Compatible with general-purpose cement, special cement, and mineral admixtures such as fly ash, slag powder, and silica fume, with good compatibility with commonly used water reducers.

◆ For concrete projects incorporating this product, mix proportion tests must be conducted in advance.

◆ This product functions more effectively in high-quality concrete; relevant specifications and design regulations must be followed to ensure concrete quality and density.

◆ Concrete adaptation tests should be performed before construction; if there is an impact on slump loss or setting time, it can be resolved by adjusting the dosage of retarders or water reducers.

◆ This product has good compatibility with commonly used water reducers but should not be mixed with acidic water reducers.

◆ Operators should wear necessary protective equipment such as masks and gloves. Waste materials and liquids must not be discarded arbitrarily.
