<p>Electrolytic protection of steel-reinforced concrete bodies such as bridges and building facades is achieved with carbon material (3, 12, 23) inserted into the concrete body (6, 10, 21). The carbon material is connected to act as a anode with the steel reinforcement (1, 11, 22) as a cathode, so that corrosive chloride ions migrate away from the steel reinforcement. The carbon material is inserted so as also to act as a reinforcement. In one arrangement carbon textile material is provided between inner and outer grout-filled plastics ducts (2, 4, 5) fixed around post-tensioned steel cables (1). In another arrangement a carbon rod (12), or pin (23), is fixed between a concrete body (23) and a steel I-beam (22).</p> |
