This document specifies the test method for obtaining bending moment-curvature curves of fibre-reinforced cementitious composites (FRCCs) through four-point bending test of prism specimens.

It is applicable to FRCCs that show separated multiple cracks under pure bending before maximum load.

NOTE

Separated multiple cracks means two or more independent cracks visible to the eye occurring in the constant moment span from the bottom side over half depth of the specimen before maximum load is observed, as shown in Figure 1. For the purpose of confirmation of cracks, spraying up the specimen surface using an alcohol solution or acetone makes observations easier. The formation of multiple cracks is associated with deflection hardening behaviour. For FRCCs that do not show separated multiple cracks, see ISO 19044.
