In splitting tensile test actually you are getting compressive strength but in answer you are writing it as tensile strength why?

Answer 1

The splitting tensile test specimen is subjected to a compressive load. For brittle matrixes such as cementitious products, the compressive strength is typically around an order of magnitude higher than tensile strength. On a microstructure scale, the compressive forces are trying to crush the individual crystallites while the tensile forces only have to fracture the connections between crystallites.

The splitting tensile test specimen fails due to the tensile forces generated as it distorts perpendicular to the applied compressive load.

In practice, a loading cap on the loading faces of the specimen generates a compressive column in the sample and the true failure is in shear along this compressive column due to the tensile forces.

In practicality, this test is also useful for flexural testing of weak composite materials where in both cases a compressive load generates tensile forces that initiate a failure that travels to the neutral axis resulting in shear as well.

Answer 2

Apologies for the confusion. In splitting tensile test, a cylindrical concrete specimen is subjected to a diametrical compressive load, leading to a splitting or tensile failure across the plane perpendicular to the applied load. The tensile strength obtained from the splitting tensile test is a measure of the material's ability to resist failure under tensile stresses.
