Advantages of Reinforced concrete pre-slab
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 shuttering. 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 shuttering.
Completing the range of construction solutions using prefabricated double walls or insulated double walls, the pre-cast slabs are made from reinforced concrete that is pre-cast to form the underlying slab of the floor, and includes all or a part of the underlying framework for the floor.
The framework size is optimized to suit each work site.
The upper facing is rough to ensure a monolithic floor structure after the compression slab was been poured.
The backing is smooth (plant finishing), ready to be painted.
The pre-cast slab represents the formwork and provides resistance to the floor.
The pre-cast slab can be used for all types of construction and adapts to all architectural constraints.
