Abstract:

Standard cube compressive specimens and central pullout test specimens are cast with C100 highperformance concrete(HPC).In the pullout test specimen,fine grain steel bars with strength grade of 500MPa are applied.After being exposed to 200 ℃,400 ℃,600 ℃ and 800 ℃,the compressive strength of the cube specimens are tested and the loadslip curves between HPC and fine grain steel bars are recorded.Based on the test results,the bond behavior between HPC and fine grain steel bars is analyzed.Finally,the difference of the postfire bond behavior between normal concrete and highperformance concrete is discussed.

Key words:elevated temperature; highperformance concrete(HPC); fine grain steel bar; bond; pullout test
