Alternative small-scale tests to characterize the structural behaviour of steel fibre-reinforced sprayed concrete

The flexural beam test EN 14488-3 is considered a reference for the characterization of post-cracking tensile response fibre-reinforced sprayed concrete (FRSC). However, geometry specimens complication in case characterising extracted from structure. double punch (DPT) and double-edge wedge splitting (DEWS) are two alternative approaches that have been introduced to simplify assessment concrete. These tests could allow characterisation samples panels or even existing structures. objective this experimental study demonstrate possibility correlate 14488-3, DPT DEWS tests, verify capacity these predicting constitutive model FRSC. results indicated high correlations (R2 above 0.98) between tests. models obtained were close those determined employing test. Both can replace systematic quality control confirmation design parameters FRSC requires more time prepare specimens, being appropriate parameterize DPT, due its simplicity execution, becomes practical Specimen with different size subjected show similar residual strength pattern.
