The present invention relates to hydraulically bonded cement compositions and methods. More particularly, the present invention is directed to novel compositions and methods of hydrating hydraulic cement without mechanical mixing of the cement and water. The present invention includes materials prepared by manipulating under pressure powdered hydraulic cement compositions using known or novel powder packing, casting, or expanding techniques, such that air within the powdered hydraulic cement is substantially removed while the cement is formed into a self-supporting near net final position. Thereafter, the formed hydraulic cement is hydrated without mechanical mixing of the cement and water.
La présente invention a pour objet des compositions de béton hydraulique ainsi que des méthodes utilisées pour favoriser la prise des compositions en question. Plus précisément, la présente invention vise de nouvelles compositions et de nouvelles méthodes pour favoriser la prise du béton sans recours au malaxage mécanique du béton et de l'eau. La présente invention vise également des matières préparées par manipulation sous pression de compositions de béton hydraulique en poudre en recourant à des techniques connues ou nouvelles pour l'emballage, le coulage et le gonflage du béton, de manière à assurer l'évacuation de l'air présent à l'intérieur du béton hydraulique en poudre lorsque le béton reçoit sa forme quasi-finale. Ensuite, le béton hydraulique est hydraté sans malaxage mécanique de l'eau et du béton.
