Securing Longevity of Reinforced Concrete Infrastructure Through Enhanced Cathodic Protection Design

澳大利亚广泛的海洋基础设施的可持续性受到腐蚀的影响，导致持续的修复和使用寿命的缩短。阴极保护（CP）是最广泛的用于恢复腐蚀损坏的混凝土，但设计原则是有争议的，不确定性存在的持续性能应如何监测。澳大利亚工业将受益于：（i）减少支出和减少对关键基础设施运营的干扰;（ii）更可持续的海事基础设施，在检查、测试、维护和修复工程方面需要更少的劳动力、时间和资本支出;（iii）有接受过钢筋混凝土保护方面高级培训的专家;（iv）更新澳大利亚保护标准AS 2832.5-2002

The sustainability of Australia's extensive maritime infrastructure is impaired by corrosion, causing ongoing rehabilitation and reduced service life. Cathodic protection (CP) is most widely used to restore corrosion-damaged concrete, however the design principles are debated and uncertainty exists on how ongoing performance should be monitored. Australian Industry will benefit from: (i) Less expenditure and disruption to operations of key infrastructure; (ii) More sustainable maritime infrastructure requiring less labour, time and capital expenditure on inspection, testing, maintenance and rehabilitation works;(iii)Availability of experts with advanced training in CP of reinforced concrete; (iv) Update Australian CP Standard AS 2832.5-2002
