Why use splitting tensile tests for concrete specimens

[nanazu]

Homework Statement

What are the benefits of splitting tensile test on concrete?

Relevant Equations

f spt MPa = 2 F / π D L

I know tensile test consist for direct tension, splitting tension, and flexural tension. Tensile test known as to know how the material behaves under the tension and to know how much of load the material can bear it before fracture. But for the splitting tensile test, i still confused. Why do we need splitting and what's the benefit f it on concrete specimens.

Many Thanks.

What is the stress tensor and its spatial distraction in a split tensile test?
