Problems with the setting of construction gypsum and Portland cement

The history of the emergence and development of construction gypsum and Portland cement is presented. The fundamental difference between the hardening mechanism and the acquisition of the physical and technical properties of these astringent substances, which consists in the direct filling of the intercrystallite cavities with water, the clouding of the first astringent and chemical interaction of cement minerals with water through the stage formation in the interphesis zone, the development and decay of transitional activated complexes - the second. The dynamics of a number of the supporting gypsum and Portland cement of the properties and phenomena that logically fit into the developed hydration models are given.
