Abstract

Gypsum binder was received by the method of intensive dehydration and the influence of admixture in phosphogypsum on the hydration process of gypsum binder was researched. Phase composition of phosphogypsum before and after calcination, using XFA, IR-spectroscopy and crystal optic analysis was defined. Dry mortar for plaster of interior walls of buildings on the basis of CaSO4·0,5H2O obtained from phosphogypsum is investigated. Its advantages and physical and chemical characteristics are shown
