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.

该项目旨在开发模型和方法，以便及早发现活跃的钢材腐蚀，澳大利亚大部分关键基础设施都位于高盐条件下的海岸或附近，并且面临着高风险的钢材腐蚀，从而增强了我们的设计能力。该项目的第一部分旨在开发一种创新的有限元模型，以改进对氯化物环境中活跃钢筋腐蚀和混凝土开裂时间的预测。破坏性方法，结合基于超声波的技术和声发射，可在结构出现任何可见损坏之前检测活跃的钢腐蚀。
