Practical considerations on the application of the recent SIA 2052 guidelines on testing of Ultra-high-performance fiber-reinforced concrete

摘要

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.
