What is the minimum thickness of a roof slab?
Also the slab thickness should be more than 4 times the nominal size of coarse aggregate in concrete mix. Generally the nominal size is 20 mm . For Roof slabs, 8 mm, Iomm, 12mm bars are used according to the Load, span of the roof slab and also it’s design factors.6mm size is used as distribution bars.
What size rebar do I need for a concrete slab?
If the concrete slab in question is meant to be the footing of a house, then #5 rebar with a diameter of 5/8-inch should be used. The above are just general guidelines, and there are several factors that will affect the right rebar size, though.
What type of steel bars are used in concrete slabs?
10 mm or 12 mm plain M.S. bars or 8 mm or 10 mm tor-steel bars are generally used. They are provided at the bottom of the slab allowing minimum cover of 25 mm of concrete.
What is the ratio of cement to concrete for a roof?
For Roof slabs, 8 mm, Iomm, 12mm bars are used according to the Load, span of the roof slab and also it’s design factors.6mm size is used as distribution bars.
