摘要： A foundation element (20), symmetrical about a longitudinal axis thereof, and formed with a crust made of at least normal-strength concrete. The crust envelops a core made of aggregate material dispersed such that the size of the aggregate material increases from fine to large about a radial section of the element.

摘要： Methode de moulage d'articles a partir d'un melange de beton. Comme le montre la fig. 1, l'eau (12) est d'abord versee dans le moule (14, 14'), et par la suite le melange de ciment sec (2) est verse dans le moule, imbibant ainsi l'eau. Une autre forme de l'invention est indiquee en fig. 2 ou, au lieu de verser l'eau dans le moule, le melange de ciment (2) est humidifie par l'eau (1) atomisee dans le melange sec juste avant de verser le melange dans le moule. L'invention est particulierement avantageuse lorsque des melanges contenant des fibres sont utilises ou lorsque les articles sont formes par moulage centrifuge.

摘要： A spin caster for spraying a surfacing material upon an interior surface of a vessel includes a spin head (53) configured to rotate about an axis, the spin head (53) including an input port (533), and a supply line (52a, 52b) coupled to the input port (533) and configured to convey a first material to the spin head (53) and a second material to the spin head (53). The supply line (52a, 52b) comprises a first channel configured to convey the first material to the spin head (53) and a second, different channel configured to convey the second material to the spin head (53).
