EXPERIMENTAL RESEARCH ON ANCHORAGE PERFORMANCE OF RECYCLED AGGREGATE CONCRETE WITH STEEL FIBER AND SILICA FUME CONCRETE

  • Publish Date: 2014-09-20
  • By the orthogonal test method,through the pull-out test of 84 specimens to investigate the bond performance between concrete and steel. Test results indicate that: 1 ) concrete cover thickness,and shape of reinforcement section have a greater effect on the failure made of bond anchorage; 2) free end slip value lagged that of loaded end,and the lag factors relate mainly with anchorage length and reinforcement diameter; 3) recycled coarse aggregate quantity of 30% pull-out specimens reached bond force limit the time compared to the ordinary concrete and recycled coarse aggregate quantity is 50% pieces for a longer period of time,the reason needs to be further explored; 4) bond performance of reinforcing steel bar and concrete is improved with an increase in concrete cover,and is weakened with an increase in the bar diameter.
