Abstract: Prefabricated element for the construction of buildings and construction method using such elements. The element consists of a monobloc element 10 made, at least in part, of prestressed concrete and having a general H shape or a shape derived therefrom, the said element comprising a horizontal floor slab 12 made of prestressed concrete joining two vertical webs 14, 16 which each extend on either side of the slab over approximately half a storey upwards and over approximately half a storey downwards, the said element furthermore comprising transverse 18, 20 and longitudinal 34, 36 horizontal bores made during prefabrication for allowing the subsequent passage of prestressing cables 30, 32; 42, 44 for assembling the element with other similar elements on a same horizontal level. Application to the construction of buildings.

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.

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.
