A regular slab for residential loads around 250 - 300mm thick would be expected to be about 1.5 - 2% steel.

Ready mix concrete is usually delivered by a concrete mixer, once delivered it is ready to use immediately. One cubic meter will cost around USD $160.

The unit weight of rebars is typically around 7.85 kg/m³. In a reinforced concrete mix with a compressive strength of 60 MPa, the amount of reinforcement steel used is usually between 1-2% of the total volume of concrete. Therefore, the weight of rebars per cubic meter of reinforced concrete at 60 MPa would be approximately 78.5 kg/m³ to 157 kg/m³.

None. Concrete may be formed without metal.If you are reinforcing the concrete with rebar then it depends on what loads the reinforced concrete will have to bear, the dimension of the rebar, the safety factor involved, and lots of other geometric factors.Steel bars quantity will be according to structure element; but a (very) rough average of 120 KG per cubic meter.
The amount of rebar in a cubic meter of concrete can vary depending on the design specifications of the concrete structure. Typically, rebar makes up around 1-2% of the total volume of concrete, so in a cubic meter of concrete, there may be around 20-40 kilograms of rebar.
The mass of a cubic metre of concrete is 2250-2400 kilograms.
One cubic meter is equivalent to 35.23 cubic feet, or one cubic meter is equivalent to 1.35 cubic yards.
