Floor slab

A floor slab (also called plate slab or filigree slab) is a reinforced concrete slab with a minimum thickness of 5–6 cm. Depending on the concrete covering and reinforcement, it can be up to 7 cm thick. The floor slab is a semi-precast component that includes the lower floor slab reinforcement that is required for structural reasons.

The floor slab is precast in the precast concrete component factory under ideal conditions, and contains the torsionally stiff reinforcement (truss) that is required to give stiffness once installed, as well as the flexural tension reinforcement, lengthways and crossways, that is required for assembly and the final state. The floor slab is made into a solid and monolithic reinforced concrete floor by using mix-in-situ concrete that is poured at the construction site. The thickness of the finished floor slab is between 12 and 30 cm, depending on the span and the loading. The protruding truss reinforcement and the concrete surface itself provide the required anchoring, ensuring good bonding and adhesion between the finished part and the mix-in-situ concrete.

Apart from some differences in the measurement of the pushing force, the floor slab can be regarded from a structural point of view as being the same as a floor that has been produced on site with concrete poured into casing. The floor slab thus combines the major advantages of prefabrication with the advantages of floors that have been produced on site with concrete poured into casing.

New Caledonia, the dream island, relies on precast concrete construction

New Caledonia, the French archipelago in the South Pacific, 2,000 km away from the Australian coast is among the world's most popular vacation destinations with temperatures between 20 and 30°C and gorgeous beaches and diving resorts. In pursuing the construction of new buildings for residential areas, public administration and touristic projects , state-of-the art precast production techniques are used. Architecturally attractive single-family homes, multi-storey residential buildings will be produced as well as hospitals, schools, entire hotel complexes and industrial halls. The precast plant of the LBDP Group in New Caledonia completed in April 2014 will produce floor slabs and double/sandwich walls as well as columns and beams in future.
