A methodology for the rational economic evaluation of reinforced concrete structures in marine environments has been developed. The durability design approach employs realistic chloride propagation models within a full life-cycle economic framework. The cost implications of variations in materials, design and rehabilitation techniques can be evaluated over the full life of the structure to achieve the most efficient use of resources. The use of cement extenders, in particular, is shown to significantly improve the resistance of concrete to chloride ions, thereby allowing for a significantly longer service life with lower initial cost.
