degree was about 50%. Also a correlation between the hydration degree and the total heat evolved was obtained. The X-ray and SEM/EDX studies have shown that K2SO4 is adsorbed at the surface of CaSO4 even within 5 min of hydration and a syngenite—a double salt K2SO4·CaSO4·H2O is formed (even in the presence of 1.0 wt% K2SO4). Also, important changes in the morphology of the dihydrate crystal are detected
