The present invention relates to an improvement to the manufacture of shelves and slabs and other concrete structural elements. According to the invention, the shelves and slabs are concreted on their pre-fitted reinforcement 6 in panels 1, 2, 3, 7 of reduced dimensions, and, after a period of time during which a considerable fraction of the shrinkage of the concrete has taken place, the fracture joints 4, 4a are closed by injecting a hardenable grout whose mechanical strength in the solid state is at least equal to that of the concrete. Application in all construction of shelves and slabs and other structural elements for concrete constructions. <IMAGE>
