The study presented in this article is focused on the influence of water soluble polymers on gypsum properties. Gypsum setting involves: gypsumhydration – crystallization and formation of polymer film in material pores. The processes are studied by various methods such as setting and mechanical measurements, scanning electron microscopy, differential scanning calorimetry and others. Polymer additives act first of all as a retarder of setting and change mechanical properties of material due to modification of its morphological structure. The mechanism of gypsum crystal grow during hydration of chemihy drate calcium sulfate was predicted to be nucleation control process (Avrami equation was applied).
