Formula to calculate length of spiral reinforcement in columns
25kg to 50kg /m3 of concrete
maximum spacing assording to IS 456 = 300mm
40 times diameter
The amount of steel required in concrete as reinforcement is measured using a formula that calculates the amount of pressure that will be put on the concrete. There are different formulas to identify the minimum and the maximum amount of needed steel, depending on if you are making a beam, slab, or column.

The minimum covering of reinforcement for roof slab is 30mm
3000 psi
25kg to 50kg /m3 of concrete
maximum spacing assording to IS 456 = 300mm
40 times diameter
minimum is less

diameter multiply by 20 times example: 8mm*20=160mm
it would depend entirely on the rebar design.....
reinforcement is video
Minimum: (AMU/30.4)*(Leadtime*SafetyStock) Maximum is the Difference between the Minimum and Buy Qty
