The effect of curing temperature of high alumina cement on the crystallization of stratlingite: In the case of curing temperatures of 10 °C and 60 °C

Abstract

Stratlingite is one of the constituent minerals of the bonding matrix of low-cement castables. In this study, the crystallization processes of stratlingite in hydrates of high alumina cement at 60 °C and 10 °C were analyzed using X-ray diffraction (XRD) and electron probe microanalyzer (EPMA). The stratlingite has crystallized in large quantities in the samples cured at 60 °C, while in the samples cured at 10 °C, stratlingite was not detected beyond the period of fifteen months.
