Re-Bar Requirement

no one can give u a quite answer

but

estimating from 2 to 3 ton ber floor

How many pounds per square foot do you want to support?

What strength concrete are you using?

What are the local building codes?

You will likely have to use mesh and bar.

As the floor slab for a typical home is not a bearing surface, it is usually an issue of the local code requirements and soil type, shrink/swell and settlement for the slab on grade. For the footings it is more complicated, the steel reinforcement depends on the soil type, bearing capacity, settlement characteristics, expansion characteristics, load pressures the footing must bear, type of footing design, size of footing, type of concrete (typically just 3000 psi standard), and seismic, wind and usage safety factors.

In order to provide you a little advice, I am afraid that you will be obliged to provide us with a little more information.

Begin with things like what country, state, community, whether or not any building code applies, and then move on to the little details like whether or not the floor is on the soil/compacted fill or elevated, are there any supporting beams below supporting the concrete floor how much weight will the floor have to support and just where are the heavier loads going to be located, what will be the strength of the concrete when it has cured, will there be a perimeter footing poured around the outside of the floor and will there be any grade beams poured beneath the slab and if so what will be their deminsions and where will they be located relative to any other support. Will there be masonry walls placed vertically on the floor that must be tied to the perimeter or interior with rebar sticking up out of the concrete ?????????? or are you planning to build a building like those that we see on television like the ones in the middle eastern desert countries. You cannot build those in most of the communities in the U.S.A.
