INFLUENCE OF THE TYPE OF POZZOLAN ADDITIVE ON THE COMPOSITION AND PROPERTIES OF GYPSUM-CEMENT-POZZOLAN BINDER
The influence of the type of pozzolan additive (the content of microsilicon, metacaolin, flask, trepel) on the composition and properties of gypsum-cement-pozzolan binder has been studied. It is shown that the best different compositions containing 4 parts of gypsum binder, 2.5 parts of Portland cement and 0.5 part (7,14%) of silica, 1 part (13,34%) of metacaolin, 1 part (18,75%) of flask, 1.5 part (18,75%) of trepel.
