Cathodic protection of concrete ground floor elements with mixed in chloride
conference paper
Corrosion of reinforcement in precast concrete ground floor elements containing mixed in chloride can cause considerable damage. This is a major problem in the Netherlands concerning a large number of privately owned houses. Conventional concrete repair is not acceptable because it does not provide sufficient durable safety. Cathodic protection was developed for protecting these ground floors for their remaining service life. The approach involves re-installing sufficient new reinforcement, activated titanium strip anodes and cementitious grouting. The monitoring system and the control procedures have been adjusted to suit the particular needs of a large number of small CP installations. It is shown that the durability of the materials and systems used will provide a service life of at least 25 years. It was found that the cost of CP compares favourably to other types of solutions
