ABSTRACT
In order to minimise costs and disruption associated with repair it is necessary to minimise the amount of concrete removed wherever practical. This also benefits the environment, with less material going to landfill, and less fresh material being employed. Cathodic protection (CP) can be used as a repair technique for chloride contaminated concrete. The main benefit is that it is no longer necessary to remove all the chloride contamination. This minimises the extent of repairs to the replacement of spalled material and can avoid the need for costly temporary support during the repair process.
