    摘要: A system and a method for molding a part from fiber cement, or fibrocement, slurry are provided. The molding is preferably made by pressure injection of the slurry. The slurry comprises cementitious material, additives, fibers and water. The fibers can include polypropylene, polyethylene, polyacrylic, cellulose, and/or asbestos fibers. First and second molding sections define, at least partially, a chamber. The second molding section comprises at least one evacuating channel. The system includes a slurry inlet communicating with the chamber, for inserting the slurry. A bladder covers the first molding section, the bladder being inflatable for compressing the slurry between the bladder and the second molding section. A filter covers the second molding section and allows water contained in the slurry to pass through while retaining the cementitious material and fibers within the chamber. A pressurized fluid inlet port communicates with at least one conduit for inflating the bladder.

    摘要: Apparatus for and a method of casting annular concrete articles such as poles or pipes. The apparatus and method comprises establishing a suitable mould (10), defining the desired mould cavity or shape (13) into which wet or uncured concrete is introduced. Thereafter excess water is removed from the concrete by pressing at least a movable internal wall (66) of the mould against the concrete within the mould cavity to pass water therefrom through drainage means (19, 20) associated with the movable internal wall to thereby provide a moulded concrete article having the characteristics of at least a partly cured concrete article whereby the mould can be removed from the article for reuse.

    摘要: Un procédé et un appareil sont utilisés pour couler des articles annulaires en béton, tels que des poteaux ou des tuyaux. Le procédé et l'appareil comprennent la formation d'un moule approprié (10) et la définition de la cavité ou forme (13) voulue du moule, dans laquelle est introduit le béton humide ou non durci. Ensuite, l'excès d'eau est extrait du béton par au moins une paroi interne mobile (66) du moule, qui exerce une pression sur le béton contenu dans la cavité du moule de façon à évacuer l'eau de la cavité par des dispositifs de drainage (19, 20) associés à la paroi interne mobile. On obtient ainsi un article moulé en béton ayant les caractéristiques d'un article en béton durci au moins en partie, ce qui permet de séparer le moule de l'article afin de le réutiliser.
