Effect of conditioned fluorine-anhydrite on the properties of portland cement

The results of testing of Portland cements containing conditioned fluorine-anhydrite from OAO Polevskoy cryolite plant as a set regulator are reported. It is shown that Portland cement containing granulated blast furnace slag and fluorine-anhydrite is characterized by a greater specific surface and higher strength compared to cements with the addition of natural gypsum-anhydrite rock.
