Résumé
Le comportement à la chaleur d’une Alite monoclinique hydratée à six mois a été suivi à l’aide de micro-éprouvettes 10×10 mm entre l’ambiance et 400°C.
Après rappel de quelques généralités, on décrit l’évolution du matériau sous ses aspects physiques: résistances, déshydratation, retrait, complétés par des examens radiocristallographiques et par spectrographie infra-rouge.
Summary
The behaviour of an hydrated monoclinic Alite on exposure to heat at six months has been observed by means of micro-test pieces 10×10 mm between ambient temperature and 400°C.
After recalling a few generalities, the paper describes the evolution of the material in its physical aspects: strengths, dehydration, shrinkage, supplemented by radiocrystallographic examinations and by infra-red spectrography.
