The double-action advanced concrete mix protects against corrosion and cracks
Nuvoco Vistas Corp. Ltd., a cement manufacturing company, launches Concreto CorroSafe – a corrosion-resistant concrete that extends the life of buildings. The advanced concrete mix design is reinforced with corrosion-resistant admixtures that act as inhibitors towards water seepage and rusting, protecting the lifespan of the structures. It is specially designed to increase the density and durability of the concrete mix.
Speaking on the product, Prashant Jha, Chief Ready-Mix, Nuvoco Vistas Corp. Ltd, said, “Corrosion is one of the single most leading causes for deterioration of concrete structures as it compromises the serviceability of the structure. Concreto CorroSafe is a differentiated solution developed at Construction Development and Innovation Centre (CDIC) to expand product basket addressing durability challenges of the structures which are severely exposed to aggressive environmental conditions. Such product solutions with prescriptive approach will help us enter specifier space to work along with consultants right from the design stage, and augment our network which is the need of the hour. Premium version CorroSafe+ is offered with specialized mix design, corrosion inhibiting additives and service life prediction for a better performance thus creating value for the customers. All this is going to enhance our brand value and improve long term profitability.”
The durability of concrete is an important parameter for the long service life of structures. The special admix of Concreto CorroSafe protects steel and other metal alloys used in construction against water-induced carbonation, and penetration by sulphate and chloride ions. Carbonation occurs when carbon dioxide penetrates the concrete and reacts with water.
The resultant reaction reduces the Ph value of the concrete, causing corrosion. Sulphate ions react with concrete, causing it to expand and crack, while chloride ions cause corrosion. Concreto CorroSafe allows the concrete cover to remain intact for longer duration. It makes the structure durable and minimises the repair and maintenance cost by increasing the service life of structures. Initially the product will be available in Mumbai, Goa, Vizag and Bhubaneshwar and later on it will be rolled out in other parts of the country as well.
With a strong and durable finish, Concreto CorroSafe is especially suitable for construction in moisture-density areas, industrial buildings, coastal buildings, as well as marine constructions like jetty and dolphin structures. As a strong foundation material, it is recommended for pile, pile caps, or any other substructures. The sturdy and dense concrete is also ideal for load-bearing constructions, such as bridges and metro stations.
