Filler Slab
Reference Project
Filler slab is an alternate slab construction technology where part of concrete in bottom of slab is replaced by filler material. The basic principal of filler slab is that the concrete in bottom half of RCC slab is structurally not required (concrete acts as compression material which is required in top half portion of slab). So this portion concrete is replaced by low cost, light weight filler material (like mangalore tile, clay pots etc). Total concrete required in this technology is about 30% less than conventional slab construction. Due to reduced concrete, self weight of the slab is reduced and thus about 40% less steel is required, without compromising strength of the slab.

Advantages
1.
Cost-effective roofing technology.
2.
Requirement of Steel is reduced due to the reduction of concrete dead load.
3.
Due to its thermal properties, it helps in reducing the temperature of the building.
4.
Filler slabs are aesthetically pleasing as they have a specific patterned symmetry.
