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

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.
