AbstractThe effect of dosage of granulated blast furnace slag and alkaline activator on the properties of
desulfurization gypsum-granulated blast furnace posites had been studied. The results indicated
,
that pressive strength flexural strength and softening coefficiency of desulfurization gypsum-

granulated blast furnace posite system were 11. 2 MPa 4. 6 MPa and 0. 42 respectively. The
properties posites were improved because the potential activity
