Minimum thickness of the flat slab is 8” or 0.2m

1.   Flat slabs or plain ceiling surface provide better diffusion of light

2.   It's economic friendly because it reduces formwork

3.   It can use where headroom Larger or storey height shorter & pleasing appearance.

4.   flat slabs are generally used in

b)  Hotels

c)   Commercial buildings

d)  Places where beam projections are not desired and where the need of aesthetics view.
