What Is a Splitting Tensile Apparatus?

A Splitting Tensile Apparatus is an accessory used together with a Compression Testing Machine to perform the Brazilian splitting tensile test on concrete specimens.

During the test, a compressive load is applied along the vertical diameter of a concrete cylinder or cube specimen. This load generates tensile stresses within the specimen until failure occurs, allowing the tensile strength of concrete to be calculated accurately.
