Abstract The article discussis the possibility of obtaining composite cements based on Portland Cement clinker and calcinedtiffite. The results of standard and special physical-mechanical tests of Portland cement with heat-treated tuffite additives are presented as a hydraulic additive. It is shown that the active mineral additive tuffit, calcined at 600ºC is suitable for production sulfate resistance cement.
