How do you find the minimum thickness of a slab?
Standards like ACI 318 have specified the minimum thickness of the slab based on the span of the slab.
- Simply Supported Slab = Span / 20.
- One End Continuous Slab = Span / 24.
- Both End Continuous Slab = Span / 28.
- Cantiliver = Span / 10.

Why minimum thickness must be provided in case of slabs?
Minimum thickness of a slab is completely dependent upon the types of slab, may be one way or two way slab, span of slab, design load upon the slab. But, the thickness is mostly depend upon the design load and the span. Other than that, the concrete mix grade also an important factor to the thickness of slab.
What is the thickness of the drop in a flat slab of 125mm thick?
