DTA Study of the hydration of systems of interest in the field of building materials manufacture.

The hydration processes of mixtures containing calcined gypsum, blastfurnace slag or fly ash, portland cement and/or hydrated lime, able to generate calcium trisulphoaluminate and silicate hydrates, have, been studied by means of differential thermal analysis. Samples were aged at 55-degrees,70-degrees and 85-degrees-C for 16, 24 and 48 hours, followed by a further curing at room temperature and humidity up to 28 days
