Crystallization of stratlingite in a high alumina cement-silica fume system with or without deflocculant
Hydration mechanism of low cement castables has been long investigated but only a limited number of studies focused on specific hydrates is available. This paper will investigate a formation of stratlingite (C2ASH8) which is believed to prevent a conversion of metastable hydrates to the stable C3AH6 in high alumina cement-silica fume systems. The stratlingite formations at 21°C and 35°C were confirmed by XRD. Its early formation at higher curing temperature is accelerated by the addition of sodium tripolyphosphate as evidenced by XRD.
