Abstract

Calcium sulfoaluminate clinker produced
through a previously described novel production
process, generating further economies of carbon
emission minimization and sulfur use efficiency, is
tested for performance as a cementitious binder. The
reactivity levels of major phases, including ye’elimite,
two polymorphs of belite and anhydrite are found to
produce a viable product characterized by rapid
hydration. Through investigation, the reactivity is
linked to the unique distribution of crystalline phases
present within cement grains. It is inferred that both
microstructure and mineralogy are responsible for the
undesirable set behaviour encountered. The causality
of this problem is further investigated and determined
to be a consequence of the intrinsic anhydrite component
for which remediation solutions are described.
The resultant mortar compression strengths are determined
for the subject cement in order to characterize
its potential in relation to ordinary Portland cement.
