Computer Program for Predicting the Service Life and
Life-Cycle Costs of Reinforced Concrete
Exposed to Chlorides

The corrosion of embedded steel reinforcement in concrete due to the penetration of chlorides from deicing salts, groundwater or seawater is the most prevalent form of premature concrete deterioration worldwide and costs billions of dollars a year in terms of infrastructure repair and replacement. There are currently numerous strategies available for increasing the service life of reinforced structures exposed to chloride salts; these include the use of:

• low-permeability (high-performance) concrete
• chemical corrosion inhibitors
• protective coatings on steel reinforcement (e.g. epoxy-coated or galvanized steel)
• corrosion-resistant steel (e.g. stainless steel)
• non-ferrous reinforcement (e.g. fibre-reinforced plastics)
• waterproofing membranes or sealants applied to the exposed surface of the concrete
• cathodic protection (applied at the time of construction)
• combinations of the above

Each of these strategies has different technical merits and costs associated with their use. Selecting the optimum strategy requires the means to weigh the increased costs against the potential extension to the life of the structure. Life cycle cost analysis (LCCA) is being used more and more frequently for this purpose. LCCA provides the means to compute the costs over the entire (design) life of the structure. Both initial construction costs and future (predicted) repair costs are included in the economic analysis. Thus, even though the implementation of a protection strategy may increase initial costs, it may still reduce life cycle costs by reducing the extent and frequency of future repairs.

LIFE-365 software predicts the service life and life-cycle costs of reinforced concrete exposed to chlorides.It is not available on this site.
