    摘要： Method of manufacturing a large-scale shell construction, wherein a form is sprayed with a setting construction material, such as concrete. The method comprises rotating the form about a rotation axis while applying said construction material. Preferably it also comprises suspending the form from above in a point through which the rotation axis runs. Furthermore, the method can comprise floating the form on a body of water.

    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.

    摘要翻译： 提供了一种用于从纤维水泥或纤维化浆料模制部件的系统和方法。 模制品优选通过浆料的压力注入来制造。 浆料包括水泥质材料，添加剂，纤维和水。 纤维可以包括聚丙烯，聚乙烯，聚丙烯酸，纤维素和/或石棉纤维。 第一和第二模制部分至少部分地限定了腔室。 第二成型部具有至少一个排气通道。 该系统包括与室连通的浆料入口，用于插入浆料。 囊状物覆盖第一模制部分，囊状物可充气以压缩囊和第二模塑部分之间的浆料。 过滤器覆盖第二模制部分并且允许包含在浆料中的水通过，同时将水泥材料和纤维保持在室内。 加压流体入口端口与用于使气囊膨胀的至少一个导管连通。
