Ceramic raw materials and ceramic materials
As the oldest man-made building material, brick must respond to steadily increasing requirements regarding its physical properties. We are working on innovations related to raw materials and the production process so as to keep brick competitive both in terms of its physical properties and its commercial viability. This research is also inextricably linked to reducing energy consumption and lowering CO2 emissions in production and processing. We conceive sustainability strategies, investigate potentials and develop approaches to the efficient use of resources and waste materials.

It’s the Process that Matters Most
Material analysis
Most road pavements are still built with asphalt, even though the significance of concrete in road construction has continuously increased in the past few decades. Requirements for road infrastructure become more and more demanding due to constantly increasing payloads in truck traffic.

Optical measuring methods
Optical measuring methods used in process monitoring are of particular interest to IAB researchers. This is where image processing systems come into play because they are easy to use in quality control. They visualise important characteristics of the material, such as its texture and colour stability. This approach is complemented by methods based on fibre optics that enable high-resolution temperature and strain measurements along the entire length of a light conductor.
