Stainless steel rebars, a cost effective and sustainable solution to the corrosion of structures
Civil engineering structures may suffer accelerated damage from the corrosion of their carbon steel reinforcement bars. This corrosion originates from the carbonatation of concrete that lowers the pH and from the diffusion of chlorides through the concrete. It generates heavy maintenance and repair costs and it significantly reduces the service life of the structures. These consequences can be avoided with the general or partial use of stainless steel reinforcement bars. This solution affords many advantages: Significant reduction of the maintenance costs. Increased sustainability. Reduced service costs. Improved safety. Optimized concrete thickness. The limited extra cost of stainless steel rebars over carbon steel rebars is quickly overcompensated for by the savings that they allow on maintenance costs.
