Title (EN) METHOD OF PREPARING AND APPLYING A SELF CURING TWO-COMPONENT POWDER/LIQUID CEMENT
(FR) PROCEDE DE PREPARATION ET D'APPLICATION D'UN CIMENT LIQUIDE/PULVERULENT A DEUX COMPOSANTS A AUTODURCISSEMENT
Abstract:
(EN) To prepare and apply two-component cement, the components are vacuum-packaged in elongated flexible fluid-tight compartments (12) and those compartments are confined in abutting relation with a seal (16) existing around the abutting portions (12b) of the compartments. One of the compartments is gradually collapsed to force its contents to break through the abutting wall portions into the other compartment while the extension of the other compartment is controlled as it receives the one compartment contents so as to enhance the intimacy of contact between the cement components. Then the other compartment is gradually collapsed to force its contents into the one compartment while controlling the extension of the one compartment as it receives the other compartment contents so as to further mix the components. The two compartments are alternately collapsed and controlledly extended until the components therein form a homogeneous cementitious mixture. Then a nozzle is attached to one of the compartments in lieu of the other compartment and the one compartment is collapsed to expel the mixture through the nozzle to the deposition site. Specific apparatus for preparing and applying the cement is also disclosed.
(FR) Afin de préparer et d'appliquer un ciment à deux composants, les composants sont emballés sous vide dans des compartiments allongés flexibles (12) étanches au fluide, lesdits compartiments étant placés bout à bout avec un joint (16) entourant les parties de butée (12b) des compartiments. L'un des compartiments est replié peu à peu afin d'amener son contenu à s'échapper par les parties de paroi de butée pour pénétrer dans l'autre compartiment, alors que l'extension de l'autre compartiment est régulée au fur et à mesure qu'il reçoit le contenu du premier compartiment de manière à rendre le contact entre les composants du ciment plus étroit. Ensuite, l'autre compartiment est peu à peu replié afin d'amener son contenu à pénétrer dans le premier compartiment de concert avec la régulation de l'extension du premier compartiment au fur et à mesure qu'il reçoit le contenu de l'autre compartiment afin de poursuivre le mélange des composants. Les deux compartiments sont repliés alternativement et allongés de manière régulée jusqu'à ce que les composants qu'ils contiennent forment un mélange cimentaire homogène. Une buse est alors fixée à l'un des compartiments en lieu et place de l'autre compartiment; ce compartiment est alors replié afin d'évacuer le mélange par la buse jusqu'au site de déposition. Est également décrit un appareil spécifique pour la préparation et l'application du ciment.
