Risk assessment modelling for corrosion affected concrete infrastructure

物理基础设施的老化和退化是一个全球性问题，它造成了广泛的过早结构失效，并大大降低了其设计使用寿命。这对澳大利亚来说也是一个日益严重的问题。对于钢筋混凝土基础设施而言，周围混凝土内部钢筋的腐蚀是最重要的因素。该项目的目的是增进对海洋环境中影响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，以便预测结构恶化和改进风险评估。

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.
