CCT diagrams of tricalcium silicate, Part I. Influence of the Fe2O3 content.

Abstract

This work studies the effect of the iron oxide content on the kinetics of thermal decomposition of tricalcium silicate, or alite, the main component of Portland cement. The experiments allowed the construction of novel continuous cooling transformation (CCT) diagrams, showing the effect of the Fe content on the alite stability, under continuous cooling.
