Abstract (en)
[origin: EP0165222A2] A concrete element for constructing a structural floor has a prefabricated base slab (1) of concrete supporting the reinforcement (2) of the element, and a concrete slab (3) cast onto said base plate. The cast-on slab (3) consists of an upper layer (5) of concrete having a compressive strength of at least 30 MPa (after 28 days) and a density of at least 2,300 kg/m<3>, and of a lower layer (4) of lightweight aggregate concrete having a density of 600-800 kg/m<3>.
