Percentage of steel in RCC is about 1-2%.
1 to 2%
Bec. the steel percentage in the concrete is very low therefor we dont deduct the steel qty. from the concrete qty.the Cocrete qty. vastage is more than used steel qty.

In construction RCC means reinforced cement concrete, however RCC Pardi is a versatile and hardy roofing material. Yes, it is composed of reinforced cement concrete. The reinforcement is typically steel.
RCC stands for reinforced concrete cement. it is a building structure made by combining the steel rod with cement concrete mixture. like beam ,pillers etc.
column curtailment details
The minimum area of steel required in RCC slab as per BS code is 0.12 to 0.15% of total area. The maximum diameter of bar in slab, shall not exceed D/8, where D is the total thickness of slab.
For a raft foundation, the amount of steel required is in RCC per square meter. This can be calculated using the value of 18 kilograms steel per square meter.
Steel Cannot be calculated based on cft. Load bearing capacity is required to calculate steel.
Bec. the steel percentage in the concrete is very low therefor we dont deduct the steel qty. from the concrete qty.the Cocrete qty. vastage is more than used steel qty.
With varying percentage of steel moment capacity varies. Since moment capacity is directly related to the stiffness of the concrete therefore more is the steel percentage in the concrete more is fc' and in turns more is the moment carrying capacity.
About 2.27 kg of steel bars is used for the RCC slab of size 50' 18' 4.5.

Concrete is very strong in compression but weak in tension. RCC is concrete with reinforcing steel bars in it. Steel is a really good material in tension. Steel carries the tensile load and thus RCC is strong in tension too. However, designers still try to ensure concrete is in compression wherever possible.

To prevent from the corrosion of steel...
You may increase the slab thickness and/or calculate the steel reinforcement required to withstand against the applied shear stress.
