Modelling and testing corroding reinforced concrete structures

该项目旨在开发能够及早发现活性钢材腐蚀的模型和方法。澳大利亚的大部分关键基础设施位于高盐分条件下的海岸或海岸附近，面临着钢筋腐蚀的高风险。我们设计和监测这种结构的能力至关重要。该项目的第一部分旨在开发一种创新的有限元模型，以提高对氯离子环境中活跃的钢筋锈蚀和混凝土开裂时间的预测。然后，该公司计划开发一种非破坏性方法，将基于超声波的技术和声发射相结合，在结构上可见任何损坏之前检测活性钢材的腐蚀。

The project aims to develop models and methods to enable the early detection of active steel corrosion. Most of Australia’s critical infrastructure is located on or near the coast in high saline conditions and is exposed to a high risk of reinforcing steel corrosion. Our ability to design and monitor such structures is crucial. The first part of the project aims to develop an innovative finite element model to improve the prediction of both active steel reinforcement corrosion and the time to concrete cracking in a chloride environment. It then plans to develop a non-destructive method, combining ultrasonic waves-based technology and acoustic emission, to detect active steel corrosion before any damage is visible on the structure.
