Anticarbonation Coatings For Concrete

Carbonation of reinforced concrete is one of the most common forms of deterioration in buildings and infrastructure. Untreated masonry is also highly vulnerable to the damaging ingress of water and freeze/thaw cycling. Carbonation is a natural process and is virtually impossible to avoid in unprotected concrete as the process begins as soon as concrete is exposed to the elements. Carbon dioxide from the atmosphere reacts with the concrete, leading to a loss of alkalinity and subsequent corrosion of the reinforcing steel. Structural integrity can therefore become severely compromised so it is critical to use anti-carbonation coatings for both new and existing structures. Such products can ensure that buildings remain visually attractive throughout their lifespan and avoid costly and disruptive repair and maintenance work further down the line.
