Abstract: This paper presents the effect of synthetic structural fiber reinforcement on acoustic emission behavior of notched fiber reinforced concrete beams subjected to flexure. Influence of synthetic polypropylene fiber reinforcement on fracture process and acoustic activity is investigated by testing concrete beams under flexure. Different acoustic emission parameters are correlated with the crack propagation and damage accumulation. Notched beams are used to simulate and study the single crack opening characteristics. The results showed that the AE location was consistent with the actual crack development. Information from the acoustic emission signal analysis reveals that in bending, the matrix cracking produces signals with less number of hits that lie in the notched plane, whereas the post peak signals corresponds to more number of hits which tend to be scattered around the plane of notch due to the fiber pull
out.
