In this contribution, the experience of the application of the SIA 2052 guidelines for testing
of Ultra-high-performance fiber-reinforced concrete (UHPFRC) at Empa is summarized.
From the point of view of testing, UHPFRC is a challenging material that sets high
requirements with regard to laboratory equipment, specimens’ preparation and evaluation of
results. The most important tests for UHPFRC classification, namely the evaluation of the
uniaxial tensile behavior and of the flexural behavior, are discussed. In particular, a practical
example illustrates to which extent probe preparation can influence the measurements of the
material properties in tension.
