Considering the different applications and methods of concrete construction, you really can't calculate it that way.
steel,cement, sand
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.

As per the civil engineering thumb rule, weight of steel for one cubic meter of concrete is 100kgs to 130 kgs for normal structures
Normal weight concrete -- a mixture or sand, cement, and stone gravel -- has an accepted density of 145 pounds per cubic foot. Since there are 27 cubic feet per cubic yard, a cu.yd. weighs 3915 pounds, or almost two tons. Complicating your question is the word "reinforced." Reinforced concrete has steel bars in it, called rebar. Steel has a density of about 490 pounds per cubic foot, which is more than three times the density of concrete, so the generally accepted density of normally reinforced concrete is 150 pounds per cubic foot which results in a cubic yard weighing 4050 pounds, but this depends on the quantity and grade of the rebar used. (Ref. AISC Steel Construction Manual, 13th Ed. Page 17-24. Also older editions have this same information.) There is light weight concrete made with lighter weight substitutes such as vermiculite for the stone and sand. These can have weights from 85 pcf. Also, there are heavy weight concretes made with steel punchings or pieces of lead used to line rooms for x-ray machines or other radioactive sources. There is a Wikipedia article on rebar, if you're interested in looking it up.
It depends on the type of structure according to the load subjected

steel
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)
Reinforced concrete is concrete reinforced with steel bars because although concrete is very strong in compression (depending on its components) it is very weak in tension and the steel bars make up for the required tensile strength.
RCC means reinforced cement concrete....in this case the reinforcement used is steel bars.....the purpose of using the steel bars in concrete it gives tensile strength to concrete to some extent.

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.
PCC is plain cement concrete. It consists of cement, sand, aggregates and water. It is good at resisting compression. RCC is reinforced cement concrete. It consists of cement, steel, aggregate and water. It is good at resisting tensile stresses also.
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.
