This European Standard deals with both large (structural) and small (non-structural or light structural) box culverts of rectangular cross-section formed monolithically and designed as continuous elements with a joint detail shaped to allow the possible incorporation of sealing materials. Box culverts can be used for creation of voids below ground for conveyance and storage of materials. e.g. conveyance and storage of wastewater, cable tunnels and subways
For the purposes of this European Standard, box culverts having internal cross-sectional dimensions (W and H in Figure 1) less than or equal to 1 250 mm are considered as small (non-structural or light structural). All other units are defined as large. The elements are generally manufactured in factories using either normal weight or lightweight concrete and usually require reinforcing steel.

Hollow core elements are used in floors, roofs, walls and similar applications. In this European Standard the material properties and other requirements for floors and roofs are dealt with; for special use in walls and other applications, see the relevant product standards for possible additional requirements.
The elements have lateral edges with a grooved profile in order to make a shear key to transfer shear through joints contiguous elements. For diaphragm action the joints have to function as horizontal shear joints.

The elements are manufactured in factories by extrusion, slipforming or mouldcasting. Fitting slabs (narrowed slab elements) and recesses to the hollow core slabs can be made during production or afterwards. Hollow core slabs can have provisions for thermal activation, heating, cooling, sound insulation, etc. Due to these provisions, the concrete temperature remains in it’s natural range.

These solid slabs have the same overall cross-section as hollow core slabs, however without hollow cores.
The application of the standard is limited for prestressed elements to a maximum depth of 500 mm and for reinforced elements to a maximum depth of 300 mm.
For both types, the maximum width without transverse reinforcement is limited to 1 200 mm and with transverse reinforcement to 2 400 mm.
The elements may be used in composite action with an in situ structural topping cast on site.
