Physical and mechanical tests of portland cement with annealed additives

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.
