DTA-TGA was used to monitor the evolution of hydration products in unstirred autoclaved metakaolin-lime-quartz slurries with reaction time. Hydrogarnet was always one of the first phases formed at all metakaolin additions and invariably appeared before 11 Å tobermorite. These findings explain apparent inconsistencies in the literature because the continued existence of hydrogarnet depends on such factors as reaction time and bulk composition. DTA-TGA indicated that the lime-quartz reaction was retarded and inferred differences in the precursor silicate anion structure of calcium silicate hydrates with increasing metakaolin addition. © 1998 Elsevier Science B.V.
