| Abstract |
| Monocalcium aluminate, a major hydraulic phase of high-alumina
cements, hydrates to form metastable CAH10 which finally converts
to stable C3AH6 and AH3• The thermal stability of monocalcium
aluminate hydrate in relation to titania was studied by thermogravimetry.
The dehydration rate curves obtained at different temperatures
in the range 100° -400°C followed formal first order kinetics.
The activation energy values of the dehydration reactions were determined
and found to be dependent on the titania content. Six per
cent titania has beneficial role on the thermal stability of the
hydrated monocalcium aluminate. |
