Whether crumbling tunnel walls, cracks in concrete facades or porous bridge piers, according to statistics from the National Association of Corrosion Engineers (NACE), damage to concrete structures caused by various environmental influences accounts for several billion euros worldwide every year. In close cooperation with the Austrian Society for Construction Technology (ÖBV) researchers at TU Graz want to contribute to the solution of this global and problem.

In the LumAConM (high-resolution luminescent analyses of construction materials) project, the consortium is working on a new, simple and cost-effective method that enables a detailed assessment of the condition of concrete structures on site as well as laboratory measurements with unprecedented precision for the first time. This enables the service life, as well as any problem areas, to be assessed much more quickly and precisely than is possible with currently available methods of analysis.

The researchers also hope that the new method will provide them with a better understanding of the course of essential corrosion processes. “This knowledge enables targeted and cost-effective refurbishment and is essential for the development of new, sustainable and durable materials,” explains Florian Mittermayr, researcher at the Institute of Technology and Testing of Construction Materials at TU Graz.
