The tensile strength of concrete is 10% of it's compressive strength.
tensile strength is approximately between .08 to .15 of compression strength in concrete
Tensile strength is one of the basic and important properties of the concrete. The concrete is not usually expected to resist the direct tension because of its low tensile strength and brittle nature. However, the determination of tensile strength of concrete is necessary to determine the load at which the concrete members may crack. The cracking is a form of tension failure.

how much tensile strength of M20 grade concrete at 28 Days
Steel is used for its high tensile strength and the concrete is used for its high compression strength.
it is the ratio of tensile strength to the flexural strength
Concrete blocks are tested for Compression and Tensile strength.
Actually concrete is not very good in tension therefore we have to introduce reinforcement which takes care of the tensile stresses. If we don't provide reinforcement, concrete will start showing cracks wherever tensile stresses overcome the concrete tensile strength.
The reinforcment will have little or no effect on compressive strength. It will however impact tensile strength. It depends on the concrete mix design and amount of reinforcment, what the tensile strength impacts will be. The question needs to be a lot more detailed to provide a specific answer.
They for strength for concrete structures. Concrete, like masonry, is strong in compression (forces downward on it) but not in tension (stretched out). Therefore the steel gives the concrete tensile strength.
Probably reinforced concrete i.e concrete with metal rods (re-bar) run through to give it tensile strength as well as compressive strength.
