Abstract: The material for injection to shroud a framework, and especially prestressed cables, is composed of 1.3-3.0 wt.% of inert hydrophilic particles in the cement mixture. They have a specific surface of more than 200 m /g, to give a fraction during mixing and/or injection into numerous fragments as small as 5 nanometres and as large as 300 nanometres. The particles are of precipitated silica.

Abstract: A concrete structure including a rigid three-dimensional lattice of concrete bars which are interconnected at nodes. The lattice is constituted by an assembly of prefabricated cast blocks, in which each block comprises a node and a plurality of arms (14) radiating from the node. Each arm has at least one longitudinal socket with an opening in the free end of the arm, and the arms of two blocks are assembled in aligned end-to end pairs to constitute the bars of the lattice. The sockets of assembled arms are in alignment and contain a common metal reinforcing member, and the junction zone of the arms is surrounded by a clamping sleeve, with the sockets being filled with hardened mortar. The lattice is prestressed by prestress cavles passing outside the bars of the lattice and fixed to some nodes of the lattice.

Abstract: The disclosure describes a process for manufacturing a concrete structural element. The process comprises placing concrete in a casing, axially compressing the concrete in the casing while the concrete is setting at an axial pressure of at least MPa, and surrounding the casing during the compressing and setting with a hoop so as to create transverse planes of pressure. The device used includes a tubular casing which extends along an axis, and is adapted for producing a hoop around the tubular casing and for compressing the concrete along the axis of the casing during setting of the concrete.

Abstract: A ballastable concrete base for an offshore platform is essentially constituted by a volume formed by a three-dimensional lattice of concrete bars interconnected at concrete nodes. Some of the nodes are interconnected by prestress cables passing outside the bars and optionally past intermediate nodes. The cables three-dimensionally prestress the lattice as a whole, and the base further includes means for making watertight the side and the bottom of the lattice.

Abstract: A prefabricated three-dimensional truss structure for a bridge, or the like, the truss formed from bars arranged to define triangular or rectangular patterns. The bars are formed from prestressed, high-strength concrete that are connected at their ends with assembly blocks that are prestressed, the prestress being preferably provided by the cables that prestress the bars, and which terminate at the blocks. A plurality of such unit trusses can be assembled to provide a truss structure for a bridge span, and the trusses can assume a wide variety of configurations.
