Abstract: The joint includes at least two profile elements having such a shape as to enable mutual engagement thereof as a male part and at least a female part, each being integral with one of the edges of two adjacent slabs. One edge of the slab is provided with a substantially L-shaped female profile, whose vertical stem extends all along the edge up to the sharp edge of the upper surface of the slab, and whose base stem extends towards the inner part of the slab and is downwardly folded to form a further stem, extending parallel to the base stem and forming a small space therebetween, for possible engagement of a part of the male profile.

Abstract: The invention concerns the reinforcement of a moldable material by means of fibers composed of a filiform body with, at each end, an anchoring device consisting a body in the shape of a solid of revolution, with transversal dimensions exceeding filiform body diameter.

Abstract: To make a continuous fiber-reinforced concrete slab, a totally free and independent slab is cast by using limited shrinkage concrete. After having carefully prepared a course, a separation sheet is layed thereon and a compressible mattress is intercalated between the concrete and the constructions or construction parts susceptible of limiting or traversing the slab.
