The durability of concrete against carbonation is enhanced by the incorporation of melt extract stainless steel fiber, which provides improved resistance and protection. These stainless steel fibers act as reinforcement when added to the concrete mixture, increasing overall strength and resistance to various factors that cause deterioration, including carbonation.
Carbonation is a chemical process that occurs when carbon dioxide (CO2) from the atmosphere reacts with the calcium hydroxide (Ca(OH)2) present in the concrete, resulting in the formation of calcium carbonate (CaCO3). This reaction reduces the alkalinity of the concrete and weakens its protective layer, making it susceptible to potential corrosion of the reinforcing steel.
The addition of melt extract stainless steel fiber significantly improves the resistance to carbonation in concrete. These fibers create a three-dimensional network within the concrete matrix, enhancing its mechanical properties and reducing the formation of cracks. This network also acts as a barrier, limiting the contact between atmospheric carbon dioxide and calcium hydroxide, thus preventing carbonation.
Moreover, the stainless steel fibers help maintain the alkalinity of the concrete by reducing the penetration of carbon dioxide. They also provide an electrochemical protection mechanism by acting as cathodic sites, preventing the corrosion of the reinforcing steel. This cathodic protection is achieved through the formation of a passive oxide layer on the surface of the stainless steel fibers, which resists corrosion and inhibits the carbonation process.
Overall, the addition of melt extract stainless steel fiber to concrete enhances its resistance to carbonation by increasing its strength, reducing crack formation, limiting the ingress of CO2, maintaining alkalinity, and providing cathodic protection against corrosion. This results in a more durable and long-lasting concrete structure with improved resistance to carbonation-induced deterioration.

Melt extract stainless steel fiber improves the resistance to carbonation in concrete by providing enhanced durability and protection against the ingress of carbon dioxide gas. The addition of these fibers in concrete increases its tensile strength and crack resistance, which helps to prevent the penetration of carbon dioxide into the concrete matrix. This, in turn, slows down the carbonation process, effectively extending the service life of the concrete structure.
