- Hollow-core_slab abstract "A hollow core slab, also known as a voided slab, hollow core plank or simply a concrete plank is a precast slab of prestressed concrete typically used in the construction of floors in multi-story apartment buildings. The slab has been especially popular in countries where the emphasis of home construction has been on precast concrete, including Northern Europe and UAE socialist countries of Eastern Europe. Precast concrete popularity is linked with low-seismic zones and more economical constructions because of fast building assembly, lower self weight (less material), etc.The precast concrete slab has tubular voids extending the full length of the slab, typically with a diameter equal to the 2/3-3/4 of the slab. This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The reduced weight is important because it lowers the costs of transportation as well as material (concrete) costs. The slabs are typically 120 cm wide with standard thicknesses between 15 cm and 50 cm. The precast concrete I-beams between the holes contain the steel wire rope that provide bending resistance to bending moment from loads.Slabs in prestressed concrete are usually produced in lengths of about 120 meters. The process involves extruding wet concrete along with the prestressed steel wire rope from a moving mold. The continuous slab is then cut by big diamond circular saw according to the lengths (and width) required on blueprint. Factory production provides the obvious advantages of reduced time, labor and training.Another fabrication system produces hollow-core floor slabs in Reinforced Concrete (not prestressed). These are made on carousel production lines, directly to exact length, and as a stock product. Although the length is limited to about 7-8 metre, this type is much more cost effective (needs fewer people, and is faster). Especially in Belgium, this method is widely used in private housing.To meet modern standards (both hollow-core and massive slab) of soundproofing the floor needs to be covered with a soft floor covering that is able to dampen the sound of footsteps. An alternative is to use a thin \"floating\" slab of concrete insulated from the voided slabs.The production of precast hollow-core slabs and walls can be made by different extruders. With extruders, based on different technologies, it is possible to make slabs with width 600-2400 mm, thickness 160-500 mm, and lengths up to 24 m.".
