It depends on its strength. Usually, concrete is 6.7 to 9 times stronger in compression.
To be exact, tensile strength of concrete is equal to 0.7 Times Square root of its compressive strength. For common concretes with compressive strength of 20 to 40 MPa, it is about 3 to 4.4 MPa of tensile strength respectively.
When you elongate any material through an axis, till some point material tries to adjust without breaking so that resistance by material is tensile strength of the material and vice versa is compression strength.

Why use rebar in concrete?
Concrete is good in compression, poor in tension. Steel is good in tension, poor in tension. By the addition of reinforcing steel into concrete, you take the strengths of one material and marry it to the weakness of the other. This provides a better product capable of better performance in the field.
What is Reinforced cement concrete-RCC?
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.
What can you reinforce concrete with?
There are different forces on a materials such as Compression and Tension. Compression is pushing a material together. Tension is pulling a material apart. Concrete has good strength in Compression, but is weak in Tension. The steel reinforcement improves the resistance to tension of the concrete.
Why do engineers use reinforced concrete?
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.
What is the difference between the singly reinforced beam and doubly reinforced beam?
A singly reinforced beam only has steel reinforcement on the tension side (along the bottom of the cross section) where as a doubly reinforced beam has steel reinforcement on both the tension and compression sides, ie. the top and bottom of the cross section.
Does Mild steel have good compression?
No, it is good in tension.
Why use rebar in concrete?

This provides a better product capable of better performance in the field.
Why steel good in tension?
Steel is good in tension because of its high tensile strength, which allows it to resist stretching or pulling forces without easily deforming or breaking. This is due to the internal structure of steel, which consists of long, strong, interlocking crystals that can distribute the applied forces efficiently, making it an ideal material for applications where tension forces are predominant.

What makes bridge so strong?
Steel and geometry, tension, straight, aches and channels make a good bridge
Which metals are strong in tension?
Steel and Titanium
Rebar is used to?
Rebar is used to give strength to masonry and concrete constructions. Masonry is this case is concrete blocks. Concrete, block or cast in place, is good for compression forces and not tension. Steel is good in tension or tensile forces and not compression. By combining the constructive elements of concrete with steel, thus reinforced concrete, you get the strengths of both in one medium.
What can you reinforce concrete with?
There are different forces on a materials such as Compression and Tension. Compression is pushing a material together. Tension is pulling a material apart. Concrete has good strength in Compression, but is weak in Tension. The steel reinforcement improves the resistance to tension of the concrete.
What material could be used for parts of a bridge which is in tension?
steel
What is important of steel in the rienforced concrete?
Concrete is basically strong in compression butWEAK IN TENSION this limitation can be compensated by providing steel as being strong in tension it takes the tensile forces and make section safe in tension.......moreover both concrete and steel have same coefficient for thermal expansion so there are no additional stresses due to temperature change.
What is the Young's modulus value for suspension system materials?
Usually a minimum of 200 GPa. This is the Young's Modulus for structural steel a common material for suspension systems. Steel is great in tension. Concrete is weak in tension.
Steel is used for cables in suspension bridges because of its capacity for?
tension :D
