Aging and deterioration of physical infrastructure is a global problem that has caused widespread premature structural failures and significantly reduced its designed service life. This is an increasing problem also for Australia. For reinforced concrete infrastructure, the corrosion of the reinforcing steel within the surrounding concrete is the most significant factor. The aim of the project is to improve understanding of the factors that influence corrosion mechanics in marine environments, to re-examine corrosion process in practical concrete structures and to develop a model for corrosion to enable prediction of structural deterioration and improved risk assessment.

有形基础设施的老化和恶化是一个全球性问题，导致广泛的过早结构失效并显着缩短其设计使用寿命。对于澳大利亚来说，这也是一个日益严重的问题。对于钢筋混凝土基础设施，周围混凝土内钢筋的腐蚀是最重要的因素。该项目的目的是提高对影响海洋环境腐蚀力学的因素的了解，重新检查实际混凝土结构中的腐蚀过程，并开发腐蚀模型以预测结构恶化并改进风险评估。
