The tensile strength of concrete generally varies from 10 % to 12% of its compressive strength.

Why Concrete Has Good Compressive Strength But Bad Tensile

Tensile strength of concrete. The tensile strength of a material is simply the measurement of the force required to pull something to the point that it breaks. In other words, you could say that the tensile strength of a material is the maximum tension it can withstand without breaking.
