摘要：
Two types of natural gypsum from different regions of Romania and two types of synthetic gypsum resulted in the flue gas desulfurization (FGD) industrial installation where characterized from compositional, structural and morphological point of view by thermal analysis, X-ray diffraction, scanning electron microscopy coupled with energy dispersive X-ray spectroscopy and laser granulometry. The mortars developed based on portland cement and different proportions of gypsum were also investigated in terms of setting time and mechanical properties (flexural strength and compression strength), in correlation with the visualization of the hydration products through scanning electron microscopy. The results were correlated with the purity and homogeneity of the analysed gypsum specimens.
