Corrosion in concrete is a major challenge facing the construction industry. Concrete setting accelerators based on chloride can seriously damage works as using them will lead to corrosion. Having a concrete admixture that works as a corrosion inhibitor is a significant benefit to the construction’s durability, be it a building, bridge, tunnel or any other infrastructure project.
In the mid 1990s, Yara developed NitCal, a purified, speciality nitrate for use as a concrete setting accelerator, which brings you a whole range of additional benefits compared to other concrete accelerator admixtures.
NitCal provides extra strength to structures by reducing the corrosion of reinforcements. This gives your construction, building or civil works, a long-lasting durability benefit and reduces life-cycle costs by diminishing repair and rebuilding costs. The maintenance costs linked to repairs and possible rebuilds are reduced. One of NitCal’s main advantage is to increase the life of the building, bridge, tunnel or any construction that you need to build.
Furthermore, NitCal is an environmentally friendly product, that is non hazardous, and that creates no alkali-aggregate reaction (AAR). NitCal can be delivered as uncoated granules or in a liquid solution. It is added to concrete either before or during its mixing to alter its properties.
