抄録

The bond characteristics considering the effects of embedding angle and length were investigated by pullout tests. Four polyolefin (PO) fibers were evaluated together with a steel fiber and a polyvinyl alcohol (PVA) fiber. Bond strength or the maximum pullout resistance of the steel fiber were several times higher than the other fibers, however, after the peak strength its pullout resistance decreased very rapidly. Bond strength of all six fibers increased from 0 to 45 degrees of embedding angle and thereafter decreased with increase of embedding angle. A very simple model was proposed to explain the effect of embedding angle on bond strength and it was found that the model has much potential to trace the tendency (increase and decrease) of the bond strength. The effects of embedding length were also investigated. It was found that the averaged bond strength of fibers except PVA fiber decreased with embedding length. On the other hand, the bond strength of PVA fiber did not show apparent decrease with the embedding length, which might be attributed to the coincidence of rigidity between the fiber and the matrix (mortar) .
