This paper investigates the response of reinforced HPFRCC in tension. 1,700-mm long specimens reinforced with 0.7, 1.7, and 3% of rebar were tested. Test results show that, except in specimen with 0.7% rebar, which failed due to rebar pull-out, the HPFRCC was capable to deform compatibly with the rebar prior to yielding. This is confirmed by uniform steel strain profile, formation of multiple cracks along the specimens, and steel response similar to bare bar. Crack localizations were observed at the post-yielding stage. A comparison the tensile response of R/HPFRCC and RC is presented. |
