For low strength class concrete, as mentioned by Saber, the tensile strength of unreinforced concrete equals 1/10 the compressive strength, and for higher class, it is about 1/15.

Research indicates that direct tension averages about 10 percent of the compressive, being about 7 or 8 percent for high-strength concrete (8000 to 10,000 psi compres- sive) and going as high as 11 or 12 percent for low-strength concrete in the range of **1000 psi compres**- sive.What is **tensile strength of concrete** - AnswersJul 26, 2010 · Concrete has almost no tensile strength on its own, which is why some form of reinforcement is used. Generally re-bar, steel shake, or fiber glass is used to improve and reinforce concrete. Epoxy has a tensile strength of at least 2,400 psi. The compressive strength is What is the tensile strength of concrete? - QuoraThe tensile strength of concrete is one of the major properties of concrete, especially in the case of making roads and runways. The tensile strength of concrete generally varies from 10 % to 12% of its compressive strength.

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.
