Title
(EN) METHOD AND APPARATUS FOR MICROWAVE AIDED SETTING OF SETTABLE COMPOSITIONS
(FR) PROCÉDÉ ET APPAREIL POUR UN DURCISSAGE ASSISTÉ PAR MICRO-ONDES DE COMPOSITIONS DURCISSABLES
Abstract
(EN)
Method for setting of settable compositions containing water of settable compositions containing water by application of energy in the form of microwaves. The settable composition is placed in a mainly isolated chamber and the static pressure in the chamber is reduced at the initial or early phase of the setting to a pressure lower than atmospheric pressure. The vapour pressure which develops in the composition during the setting reaction is compensated by a pressure increase, counterpressure, in the chamber, whereby an exchange of water molecules may take place at the surface of the composition without damaging the composition by way of pore formation. An apparatus for the purpose of conducting the method is also described.
(FR)
L'invention concerne un procédé de durcissage de composition réglable contenant de l'eau grâce à un apport d'énergie sous forme de micro-ondes. La composition durcissable est placée dans un compartiment essentiellement isolé et la pression statique dans le compartiment est réduite, lors de la phase initiale ou précoce du durcissage, à une pression inférieure à la pression atmosphérique. La pression de vapeur qui se développe dans la composition pendant la réaction de durcissage est compensée par une augmentation de pression, une contre-pression, dans le compartiment, grâce auquel un échange de molécules d'eau peut avoir lieu à la surface de la composition sans endommager la composition par le biais d'une formation de pores. Un appareil destiné à mettre en œuvre le procédé est également décrit.
