In the presented paper, the applicability of the wedge splitting test for determining fracture properties of fiber-reinforced concrete is discussed and results obtained when using different specimen geometries are compared. This is based on experiments on steel fiber-reinforced concrete, with different mix proportions and fiber geometries, and non-linear fracture mechanics analyses. Furthermore, a general discussion of the wedge split test method when applied to FRC is presented, e.g. requirements on the test set-up, specimen geometry, data analysis techniques to determine the tension softening relationship, etc.

Nyckelord: Wedge-splitting test, fiber-reinforced concrete, fracture mechanics.
