Anti Carbonation Coating - A Shield to Concrete against Carbonation

What is Anti Carbonation Coating ?

Anti Carbonation Coating

Anti-carbonation coating is a protective coating applied to concrete structures to reduce the effects of carbonation. Carbonation is a chemical reaction in which carbon dioxide from the air reacts with the calcium hydroxide in concrete to form calcium carbonate. This process can lead to a reduction in the alkalinity of concrete, thus compromising its durability and damaging the materials.

These coatings are commonly used in infrastructure projects, commercial buildings, parking structures, bridges, and other concrete structures that are exposed to environmental conditions. They play a crucial role in maintaining the durability and structural integrity of concrete, and overall structure.

The Role of Anti Carbonation Coatings

Anti-Carbonation coating is known to protect concrete and masonry structures with high exposure to carbon dioxide, sulphur dioxide, chloride irons, etc. It is a single-component, high-performance acrylic resin-based coating that safeguards the wear and tear of the structure against corrosive materials for the long term. Anti carbonation coating is critical in maintaining the structural integrity of both new and existing structures.

Anti carbonation coating makes a structure visually attractive and reduces the cost of maintenance and repair throughout its lifespan. Anti-carbonation coating for concrete floors is essential, but considering other structural components exposed to concrete such as beams, columns, slabs, and restraining RCC walls also require anti-carbonation coating. Bridges and flyovers, overhead tanks, industrial buildings, and power plants use anti-carbonation coating techniques for protection.

Benefits of Anti Carbonation Coating

  • The anti-carbonation coating is known to be an extremely durable and stable form of protection.

  • Anti-carbonation coating is capable of allowing moisture inside the concrete to respire out.

  • The process of anti-carbonation coating has the flexibility to deal with minor cracks that form in concrete.

  • Extends the lifespan and Improves the appearance of concrete structures.

  • Reduces maintenance costs.
