【 摘 要 】

Determination of the input material quality is crucial for calcination and for gypsum wallboard production itself. The article focused on the practical use of analytical methods in building practice. It presents procedures on how to determine the content of calcium sulphate in the raw material as well as the results from real measurements of the raw material samples, further calculation and evaluation. Together four samples from three different sources located near the potential gypsum wallboard production line were analysed using X-ray Diffraction (XRD) and Thermogravimetry (TGA).
