Utilisation of secondary raw materials
It is crucial to characterise the starting materials as well as the reaction products in detail. The starting materials can be technical products (e.g. cement) or are synthesised in the laboratory itself. Central methods for mineralogical and chemical analyses are X-ray diffraction (XRD) and X-ray fluorescence (XRF). The microstructure, which significantly influences the macroscopic properties, is analysed using light and electronic optical methods. In order to measure the various parameters influencing the hydration of inorganic binders, such as pressure, temperature, grinding fineness, etc., the Mineralogy/Geochemistry department has access to autoclaves, thermogravimetry, heat flow measurement (DCS, heat flow calorimetry), particle size distribution (standard sieves, laser granulometry) for the corresponding experiments and analyses. The combination of the knowledge gained then allows conclusions to be drawn about the reaction kinetics. From this, conclusions can be drawn about the durability and optimisation of cementitious systems.
