Concrete usually fails suddenly under thermal load. Nevertheless, concretes are already being used in technical areas under cyclic thermal load. Special micro-reinforcement can prevent failure at temperatures in the 200-500 °C range. Nevertheless, there is a need for concretes with a higher resistance due to increasing demands. Faster heating rates and higher temperatures represent the increased requirement profile here.

The applicants have set themselves the goal of optimizing a very dense and durable concrete (ultra-high performance concrete, UHPC) for this requirement profile and adapting it to the corresponding production processes. Based on current results, a UHPC optimized for thermal loads is to be researched and optimized for the use of baking plates. In addition to thermal resistance, this concrete has other advantages. Furthermore, this high impermeability is also expected to result in a high heat capacity, which would be advantageous for the food production process in baking ovens.
