Although not used as often as compression tests for concrete, tension tests are needed in order to fully assess structural performance. Because axial tension tests are difficult, many alternative methods have been tried though only a few are specified in standards. This Digests covers the five principal categories of tension tests: axial, splitting, flexure, fluid pressure and torsion. Variations of these are described, discussed and compared. All the methods have their uses: the choice depends upon the application and the structural context, and the practical considerations of performing the test.
