Competence Center for Material Moisture (CMM)

5th CMM Autumn School

    Hotel Erbprinz, Ettlingen

    October 8-9, 2019

  • Aim of the Autumn School is to present the state of knowledge of water binding and moisture measurement in soils, clays and construction materials. The Autumn School focusses particularly on the needs of young scientists (MSc , PhD students and PostDocs) but is open to all who work in the field either in science or application.

     

    The first day covers mineralogical, chemical and physical fundamentals of moisture measurement. Fundamentals comprise mineralogy of clay minerals and other minerals and their water binding mechanisms as a reliable calibration of in-situ moisture measurements requires understanding of structure-functionality-relation of mineral materials. After an introduction into the dielectric properties of water, the effect of solutes will be discussed for aqueous solutions of electrolytes and of nonpolar and polar organic molecules. (Semi-)empirical approaches and mixture equations as well as broadband relaxation models will be illustrated for transformation of measured permittivity into water content. Finally, various dielectric techniques and sensors for moisture measurement in soils, clays and building materials will be shown.

    The second day provides the opportunity for extensive discussion amongst participants after keynotes that cover the importance of water content in soil science, clay science and construction.
