Abstract

Synthesis of the portland cement clinker in the presence of a significant amount of SO3 is difficultdue to the tricalcium silicate formation suppression. Since some technogenic formations contain a significant amount of SO3 it is hard to obtain the portland cement clinker from it. The analysis of the SO3 influence on the clinker–formation thermodynamic process allowed to reveal a number of regularities of their occurrence and to propose a method for the raw mix composition calculating and its preparation toensure a stable portland cement clinker synthesis.
