Testing hardened concrete — Part 21: flexural strength and fibres contribution of UHPFRCs on prism test specimen cen:proj:83241

Scope

This document specifies the procedures for characterising the tensile performance of UHPFRCs through bending tests, when the orientation of the fibres is not influenced by a reduced member thickness relative to the dimension of the fibres.
Two types of test are described:
- four-point bending tests on un-notched prisms which enable the limit of linear behaviour to be ascertained;
- three-point bending tests on notched prisms which enable the contribution of the fibres as reinforcement of a cracked section to be ascertained and the tensile behaviour class determined.
