- Description
- Increases in atmospheric CO₂ concentrations, and changes in temperature and humidity due to a changing climate will, especially in the longer term, cause an acceleration of deterioration processes and consequently acceleration in the decline of the safety, serviceability and durability of concrete infrastructure. An investigation of concrete carbonation-induced deterioration in typical Australian and Chinese cities under a changing climate is described in this paper. It is based on Monte-Carlo simulation analysis that involves three emission scenarios, i.e. A1B, A1FI and 550 ppm stabilisation. The probabilistic analysis included the uncertainty of climate predictions, deterioration processes, material properties, dimensions, and predictive models. Deterioration of concrete structures is represented by the probability of reinforcement corrosion initiation and corrosion induced damage at a given calendar year between 2010 and 2100, and all of them are affected by the changing climate depending on locations. It was found that carbonation depths may increase by more than 45% for inland locations in Australia. It was also found that carbonation-induced damage risks can increase threefold by 2100 to 2% for Canberra. The findings provide a basis for the development of climate adaptation strategies through the improved design of concrete structures.
