Splitting tensile strength

The splitting tensile strength is an experimentally determined figure that is used to evaluate the tensile strength of concrete . ${\displaystyle \beta _{SZ}}$

It is determined by clamping a concrete cylinder across its center line and increasing the pressure until the cylinder breaks. The splitting tensile strength results from this as follows:

${\displaystyle \beta _{SZ}={\frac {2\cdot F}{\pi \cdot d\cdot l}}}$

With

• F = compressive force when the cylinder breaks
• ${\displaystyle {\frac {\pi \cdot d\cdot l}{2}}}$= half the surface area of the cylinder
  • d = diameter
  • l = length.

It is  dealt with in various DIN standards (such as EN 12390-6, 22024, 1048).
