  1. * Notes: a The results of tensile test are the average values of three specimens with the same configurations.
  2. bThe sleeve was not fully filled with the grout, and therefore, inadequate bond strength was generated. For this, the results for WBS-4 were not representative, and hence, it is discarded from the analysis.
