It deals with the tension and compression of the concrete. Concrete is a really great material when in comes to compression. It has a high strength in compression but little in the way of tension. You can test this for your self. Get a small unreinforced piece of concrete and pull it apart it ( put it in tension) and it breaks fairy easily. Now, try pushing together (put it in compression) and it doesn't break anywhere near as easily, if you can break it at all. Steel is the opposite. It has more strength in tension than in compression. Putting steel bars in concrete allows you to have good strength in compression and in tension. In an easy way to understand it and get the general idea, when the reinforced concrete is under tension, the steel bars take over, and when the reinforced concrete is under compression, the concrete takes over.

you could strengthen it by putting metal bars inside the concrete

yes we can pour concrete to steel bars painted with red oxide. this will help steel bars from getting corroded.

The quantity of steel bars, better known as rebar, in a 1 m cubic amount of concrete is dependent upon the use of the concrete. The more steel bars in the concrete the higher the weight rating of the concrete will be.

Deformed steel bar is more commonly known as reinforcing bar, or rebar. These steel bars are imbedded in concrete to provide tensile strength. Smooth bars are run through rollers which "deform" the bar thereby adding ribs. The ribs provide a mechanical bond between the steel bars and the surrounding concrete.

RCC means reinforced cement 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.

It is steel bars with small deformations that prevents the steel from slipping when encased in concrete. The shape of the deformations may be different depending on the strength of the bars.

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.

Steel bars laid in concrete to reduce cracking do to temperature change

Steel is stronger than concrete. By adding some reinforcement in the compression zone of a beam, it's bending strength can be increased without increasing the size of the beam. The steel increases the compression strength, while the concrete prevents the slender steel bars from buckling.

Reinforced concrete has steel bars embedded in it. It is also called re-barred concrete.

Mild steel bars are used for stress of reinforced cement concrete beams and concrete. The tor steel are used as lugs and ribs and are to minimize slippage.

Reinforced concrete is made by placing steel bars in the tension zone of the beam x-section.

i think but am not entirely sure that it is made from steel bars and concrete

the concrete cover protects the steel bars from corrosion and environments or members more prone to corrosion or chemical attack such as in footings the cover thickness is increased in members where the concrete will come to direct contact with the soil a blinding layer of about 10cm is used to separate the reinforced concrete from the soil. also coating steel bars in corrosion resisting chemicals is used for more protection

their concrete steel bars hold them up nice and straight

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.

Generally with steel reinforcing bars (sometimes fondly known as rebars). Steel rebars are provided in tension zone of the beam x-section as concrete in very weak in tension.

The reinforcement may be in the form of "mesh" or rods. The steel reinforcing rods are colloquially called rebar(reinforcement bars).

Concrete is a material which is extremely effective when loaded in compression, yet performs poorly when loaded in tension. Steel on the other hand is quite effective in tension. Reinforced concrete uses steel bars wherever the concrete is loaded in tension in order to increase its capacity.

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.

Concrete are used without reinforcement bars on concrete roads.
