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.
