Risk assessment modelling for corrosion affected concrete infrastructure

点击翻译按钮获取中文摘要

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.
