Description

High-resolution Luminescent Analyses of Construction Materials
The pH and chloride content of concrete-based construction materials are key parameter for the assessment of their stability and long-term performances, since major types of chemical degradation mechanisms such as carbonation, chloride induced steel corrosion, as well as leaching and acid attack are strongly associated with a change of the latter. The aim of this project is to explore luminescent analytical methods as an advanced technique for the measurements of pH and chloride on and in concrete-based materials in order to determine the state of repair of concrete constructions and to increase the understanding of ongoing corrosion processes. The main goals can be summarized as follows:
- Target-oriented development of high-resolution imaging system for pH, chloride and potentially further relevant ions (e.g. potassium and calcium).
- On-site application of the measurement method as a simple, fast and economical analytical tool for the state-of-repair of concrete infrastructure (e.g. miniaturized probes and/or sensor particles).
- Improvement of the process understanding of important alteration processes in concrete and elaboration of recommendations for applications & material developments.
