Abstract

The present invention relates to a method of manufacturing a hollowcore concrete slab comprising fixing an active reinforcement to a table (1), the table (1) extending along a longitudinal direction (9), the table (1) comprising a table surface (2), the active reinforcement extending above the table surface (2) and parallel to the table surface (2) along the
longitudinal direction (9) of the table (2); prestressing the active reinforcement; pouring concrete into a mold formed by the table (1) and at least two side walls (18); curing the concrete into a hollowcore concrete slab; removing the hollowcore concrete slab from the mold (1); wherein a passive reinforcement is provided in the concrete after the concrete has been poured and before the concrete has cured. The invention also relates to a table (1) for manufacturing a hollowcore concrete slab and a use of the method or the table for manufacturing a hollowcore concrete slab.
