Thaumasite formation by hydration of sulphosilicate clinker

Popis výsledku v původním jazyce

This work was aimed at hydration of ternesite based clinkers at low temperatures, with respect to thaumasite formation. Five clinkers with various compositions corresponding to stoichiometric ratios of elements in thaumasite and ternesite were prepared. Clinker-water suspensions were stored at 5 °C for up to 810 days. X-ray diffraction, DSC/TG, and SEM/EDS were used as the analytical tools. All the clinkers contained ternesite, belite, anhydrite, and free lime. As shown by the results, ternesite and belite preferably hydrate to CSH gels, and sulphate ions forming ternesite become a part of gypsum. The remaining portion of gypsum originated from anhydrite hydration. Gypsum reacted with silica and carbon dioxide to form thaumasite. Thaumasite was clearly identified already after 28 days of hydration.
