This document specifies a test method for evaluating direct tensile resistance of strain-hardening fiber-reinforced cementitious composites (FRCCs) using tensile parameters. The tensile parameters are determined from the measured tensile stress versus strain curve obtained by testing a specimen under uniaxial tension without any parasitic bending moment during the test.
This test method provides tensile stress versus strain curve, first cracking strength, post cracking strength, strain capacity (strain at post cracking point), toughness (area under tensile stress versus strain curve until post cracking point) and the number of cracks within gauge length. This test method is intended primarily for use with FRCCs that exhibit strain-hardening behaviour. This test method is not intended for materials that exhibit strain-softening behaviour.
