The amount of steel reinforcement required for a 1 m³ slab of concrete typically ranges from 80 to 150 kg, depending on the design and load requirements. A common guideline is to use approximately 0.5% to 1% of the concrete volume as steel reinforcement. However, the exact quantity can vary based on factors such as slab thickness, structural specifications, and local building codes. It's always best to consult a structural engineer for precise calculations.

well the density of concrete can vary from 2200kg/m3-2800kg/m3 but 2400kg/m3 is the most common
120 kg/m3
weight of hardened concrete + 100 kgf/m3
many projects have Detail drawings such as structural, electrical, plumbing, roof etc. The detail drawings use for high rise buildings, apartment, etc. in that projects can be calculate weight of reinforcement using structural drawings and preparing bar schedule. some small projects have only architectural drawings . there has no include structural detail drawings, hence we have to calculate weight of reinforcement separately column, slab, beam lintel, plinth beam, cantilever slabs and beams, That are showing below....PER 1 M3...............!!in between 100 - 110 kg/m3 for column,in between 110 - 120 kg/m3 for slab,in between 120 - 130 kg/m3 for beam ........................ !!!Then add these with weight of non reinforced concrete.weight of concrete 2400 kg/m3

It all depends on the type and sizes of the steel used. It also depends on the load that the concrete has to take at certain points. 7865kg is the weight of a cubic meter of steel. Typical examples; A pile cap could contain 400kg/m3 A heavy duty industrial slab or structure could contain 200kg-400kg/m3 A footpath could contain 40kg/m3 (all depends on the design, but numbers above should give you a rough answer)
For a 1000 sqft slab with a thickness of 4 inches, you would need approximately 33 cubic meters of concrete. This calculation is based on the assumption that 1 cubic yard of concrete covers 81 square feet at 4 inches thick.
If you know the dimensions of the slab, assuming that the slab is solid and in the shape of a rectangle, box, or square, you can calculate the volume with the formula: LxWxH which is length times width times height. This will give you the volume of the slab in cubic units (meters, feet, inches, whatever). Depending on the type of steel, you will have a different density ratio which can be used to calculate the weight of the slab. The density of low grade steel is something on the order of: 7850 kg/m3 so you would multiply your volume by the density ratio to get kilograms. If you know the weight of the slab and the type of steel, you can calculate the volume by dividing the weight by the density ratio. I hope this helps, perhaps you could provide more details on the type of steel and the exact property of the slab that you need (volume, weight, density.

Concrete has a density of about 2,3 tonnes per cubic meter (varying slightly with the type and amount of ballast). 2400 kg/m3 may change depending on the mix design. You can also get lightweight concrete at 1750 kg/m3. k.k
