BS EN 1168 deals with the requirements and the basic performance criteria and specifies minimum values where appropriate for precast hollow core slabs made of prestressed or reinforced normal weight concrete according to EN 1992-1-1:2004. BS EN 1168 also deals with solid slab elements used in conjunction with hollow-core slabs and manufactured by extrusion, slip forming or mould casting, equivalent to the manufacturing of hollow-core slabs. These solid slabs have the same overall cross-section as hollow core slabs, however without hollow cores.
Note 1: BS EN 1168 does not deal with complementary matters. For e.g., the slabs should not be used on roofs without additional protection against water penetration.
Note 2: Floors and roofs of buildings, including areas for vehicles in the categories F and G of EN 1991-1-1 which are not subjected to fatigue loading. For building in seismic zones additional provisions are given in EN 1998-1.
Note 3: The application of BS EN 1168 is limited for prestressed elements to a maximum depth of 500 mm and for reinforced elements to a maximum depth of 300 mm.
BS EN 1168 on precast concrete products for hollow core slabs is useful for:
A hollow core slab is a monolithic prestressed or reinforced element with a constant overall depth divided into an upper and lower flange connected by vertical webs, forming cores as longitudinal voids with a constant cross-section and one vertical symmetrical axis.
BS EN 1168 covers terminology, performance criteria, tolerances, relevant physical properties, special test methods, and special aspects of transport and erection. BS EN 1168 specifies the material properties and other requirements for floors and roofs are dealt with for special use in walls and other applications.
Overall, you can utilize BS EN 1168 to manufacture hollow-core slabs for the building site.
