Resumo: | This paper analyzed the effect of different fibres on the residual compressive strength, the ultimate load and flexural toughness, the failure pattern and the fracture energy of self compacting high-performance concrete (SCHPC) after exposure to various high temperature. The micro polypropylene fiber (PP fiber) could mitigate the spalling of SCHPC member significantly, but did not show clear effect on the mechanic properties of concrete. The macro steel fiber (SF) reinforced SCHPC showed higher flexural toughness and ultimate load before and after high temperatures. The mechanical properties of hybrid fibre reinforced SCHPC (HFSCHPC) after heating were better than that of mono-fibre reinforced SCHPC. The failure mode changed from pull-out of steel fibers at lower temperature to broken down of steel fibers at higher temperature. The use of hybrid fibre can be effective in providing the residual strength and failure pattern and in improving the toughness and fracture energy of SCHPC after high temperature. |

This paper analyzed the effect of different fibres on the residual compressive strength, the ultimate load and flexural toughness, the failure pattern and the fracture energy of self compacting high-performance concrete (SCHPC) after exposure to various high temperature. The micro polypropylene fiber (PP fiber) could mitigate the spalling of SCHPC member significantly, but did not show clear effect on the mechanic properties of concrete. The macro steel fiber (SF) reinforced SCHPC showed higher flexural toughness and ultimate load before and after high temperatures. The mechanical properties of hybrid fibre reinforced SCHPC (HFSCHPC) after heating were better than that of mono-fibre reinforced SCHPC. The failure mode changed from pull-out of steel fibers at lower temperature to broken down of steel fibers at higher temperature. The use of hybrid fibre can be effective in providing the residual strength and failure pattern and in improving the toughness and fracture energy of SCHPC after high temperature. |
