Disadvantages of Filler Slab – Know Before Construction

Filler slabs are unique, innovative, and modern technology for slab construction. To construct these slabs, concrete and steel are used together to cover up their limitations. 

Concrete has a firm compression, while steel is good at tension.

So the tension is at the bottom and compression on the top. If we need to optimize the structure, it’s possible to remove concrete from the tension area where the need for concrete is not that much. That is the exact principle behind the filler slab construction.
