The steel rods are there to strengthen the concrete - making it reinforced concrete.
Steel reinforced concrete is concrete with rods of steel running through it.
Mainly re-enforced concrete (concrete that's been set around steel rods). The cables are made from many long strands of steel.
The reinforcement may be in the form of "mesh" or rods. The steel reinforcing rods are colloquially called rebar(reinforcement bars).
Rebar: The steel rods that are sued to reinforce concrete or masonry (bricks or concrete block).
Lets' look at this from a simplistic point of view. The predominant factors when dealing with a bridge is strength and weight. The strength of the bridge is how much load it can handle. The weight is how much the bridge weighs before loads (such as cars) are applied. The weight of the construction material must be included when considering the total strength of the bridge. For instance, if a bridges strength is 110 pounds, and the weight of material is 100 pounds, then you can only put 10 pounds on the bridge before failure. Bridges can be made from any material. Wood is commonly used on hiking trails, Composite (Plastics) have been used on some small bridges. However, the two most popular are Steel, and reinforced concrete (Reinforced Concrete has steel rods inside the concrete to increase the strength). The reason for this is because of the incredible strength of the steel or concrete per pound of material. This allows for a very strong structure that does not generate a lot of weight. This means that the load carrying capacity of the bridge is maximized. Furthermore, the structural design of a bridge allows for load shifting. This explains the grid pattern above, or below, some bridges, the big arch under some concrete bridges, or the characteristic look of suspension bridges.
TMT Bars - High strength deformed steel bars used for concrete reinforcement. The surface has many short ribs to allow the concrete to adhere better than if the bars had a smooth surface.MS Rods - Mild Steel rods are used to construct many things (such as scaffold construction), but are not the best choice for concrete. The surface of the rod is smooth, so it does not allow the concrete to adhere as well as if the surface had a texture.

I think you are talking about embedding steel rods (rebars) in concrete, right? This would make the concrete much stronger. It is called reinforced concrete, and you can make all sorts of structures with it, something that you can't do with ordinary concrete. Though, I am not even sure anyone is using non-reinforced concrete nowadays.
Steel electrodes and rods are. Not stainless steel.
It's simply hardened steel that's been cast in long rods. It's used as reinforcing when pouring concrete to increase the strwength - especially in road construction or building foundations.
It would all depend on what the material is. Different material, different molecular composition.Composite MaterialsThere are different kinds of strength- tension (pulling) ?. steel rods- compression (pushing) ?. concreteTo enable the structure to withstand both types of forces acting on it, a composite material is used - reinforced concrete(concrete poured over steel rebar (rods).
They do not expand equally, therefore the aluminium might crack the concrete on a hot day (or vice versa) due to this difference in expansion. i.e steel rods can be used to reinforce concrete because both materials expand equally.
