cement fine aggregates and course aggregates and water for the hydration of cement are the main component of plain cement concrete. and for RCC M-S bars are used with these component.
As I would interpret the question, I would refer to the nature of reinforcing to be placed within the concrete. Often in large beams, the reinforcing steel may be made up separately in "cages" and set in place for the concrete pour. The reinforcing may be comprised of shear, bending, torsional, and specialized support components.

Mixture
Concrete is considered a heterogeneous mixture because it is composed of various components such as aggregates (like gravel and sand) and cement that are visibly distinguishable.
Wood, masonry, concrete, metal, glass, plastic.
Well this is not quite true. Aggregate is a key component of concrete and is inelastic. In addition concrete pillars and beams will bend slightly under load and is thus not 100% inelastic. Polymer modified concrete and rebar modified concrete is also slightly elastic.
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.
Concrete is a heterogeneous mixture. It is made up of various components such as cement, aggregate (like sand or gravel), and water. These components are physically combined, but they do not chemically react to form a new substance.
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
Concrete is a mixture, not a pure substance. It is made up of various substances such as cement, water, aggregates (sand, gravel), and additives. Each of these components retains its own properties and can be physically separated from the others.
