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 concrete would be weaker, and more prone to cracking.
well , reinforcement steel required for slab is nearly 0.7 to 0.8% of the volume of concrete so if concrete is 1 cum then steel will be 1*0.7/100 =0.007 but density of steel is 7850 kg/ cum so 0.007*7850=54.95 say 55 kg per cum so steel required to reinforce 1 cum concrete for slab is approximately 55 kgs.

structual steel is the widw flange column's and beam's as well as plate steel angle iron ect.. it falls under aws D1.1 welding code. reinforcement steel/reinforcing steel is the rebar, dba,(deformed bar anchor), hsa, (headed stud anchor) that is placed in concrete, floors, walls, footings, ect... it falls under aws D1.4 welding code

Reinforcement
to support the concrete
The reinforcement may be in the form of "mesh" or rods. The steel reinforcing rods are colloquially called rebar(reinforcement bars).
The concrete would be weaker, and more prone to cracking.
Under reinforcement is safe because in this case steel fails before concrete.

Items used to reinforce concrete are wire mesh, rebar, and steel cables.
The amount of steel reinforcement in a concrete retaining wall is typically measured in terms of kilograms per cubic meter (kg/m³). The exact quantity of steel reinforcement required can vary depending on factors such as the design specifications, load requirements, and the dimensions of the retaining wall. In general, a common range for steel reinforcement in concrete retaining walls is between 60 to 150 kg/m³, but it is crucial to consult with a structural engineer or refer to specific design guidelines for an accurate calculation.
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.
It proves shear reinforcement in the beam.
