Filler slab is based on the concrete portions and instead of placing filler material there and is one cost effective roofing system.
Filler slab roofs advantages.
Thus the filler slab as the roof has the following advantages.
The most popular filler material is the roofing tile.
Hence we are elimi.
The filler slab is a mechanism to replace the concrete in the tension zone.
By reducing the quantity and weight of material the roof become less expensive yet retains the strength of the conventional slab.
Rcc is composite material where concrete is strong in compression and weak in tension.
Concept the filler slab is based on the principle that for roofs which are simply supported the upper part of the slab is subjected to compressive forces and the lower part of the slab experience tensile forces.
Due to the reduction of concrete volume the overall cost of slab is lower than solid slab even after considering additional cost of mangalore tiles.
Consumes less concrete and steel due to reduced weight of slab by the introduction of a less heavy low cost filler material like two layers of burnt clay tiles.
The filler material thus is not a structural part of the slab.
This image shows a beam.
Where the area above the neutral axis is the compression zone and the area below the neutral axis is tensile zone.
Slab thickness minimum 112 5 mm.
The filler slab is based on the principle that for roofs which are simply supported the upper part of the slab is subjected to compressive forces and the lower part of the slab experience tensile forces.
Thus the filler slab as the roof has the following advantages.
Filler slab technology is a simple and a very innovative technology for a slab construction.
