There are many advantages of filler slab like the introduction of a less heavy low cost filler material it consumes less concrete and steel and reduced weight of the slab.
Filler slab roofs advantages.
Enhances thermal comfort inside the building due to heat resistant qualities of filler materials and the gap.
Consumes less concrete and steel due to reduced weight of slab by the introduction of a less heavy low cost filler.
Thus the filler slab as the roof has the following advantages.
Filler slab is alternate slab construction technology where part of concrete in bottom of slab is replaced by filler material due to reduced concrete and thus about 40 less steel is required so these fillar slab technology make huge difference between normal slab cost and fillar slab cost.
Due to heat resistant qualities of filler materials and the gap between two burnt clay tiles it enhances thermal comfort inside the building.
Due to reduced concrete self weight of the slab is reduced and thus about 30 less steel is required without compromising strength of the slab.
