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.

How do you strengthen concrete?

you could strengthen it by putting metal bars inside the concrete

Can you pour concrete to steel bars painted with red oxide primer?

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

How many quantity of steel bars for 1 meter cubic concrete?

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.

What does deformed steel bar mean?

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.

What is rcc?

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.

What is deformed steel bars?

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.

When concrete is poured around steel bars what kind of a material does it form?

reenforced concrete

What is reinforce concrete?

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.

What does shrinkage temperature steel do?

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

When does plain concrete become reinforced?

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

What is the purpose of compression reinforcement in beams?

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.

What is deformed bar?

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.
