ABSTRACT

ABSTRACT: Fibres are well known to provide post-cracking energy to concrete, enhancing the energy absorption capacity (toughness) of the material. However, variations of toughness performances of FRC are a well-known limitation for its use in structural applications. This shortcoming is not only caused by the heterogeneity of the material itself. It is also emphasized by the test method used to determine the FRC properties. This paper presents the results of an extended test programme on FRC. Four testing methods are compared. Special attention is paid to the analysis of the variation on the results since this variation indicates the power of discernment of a test method. A strong correlation (R2 > 0.99) has been found between the results of the round panel test and the RILEM beam test for the same deflection/cracking level.
