Abstract:In order to study the pre-peak damage process of polypropylene fiber reinforced concrete, typical acoustic emission (AE) characteristics in the damage processes of the polypropylene fiber reinforced concrete and plain concrete under splitting was described in this paper. Polypropylene fibers of varying contents were used as reinforcement in concrete specimens. Their influence on the damage process and the AE activity was investigated compared with the plain concrete specimens. Analysis revealed that particular AE parameters change monotonically with the progress of damage, which can be applied for the failure process characterisation. The results have shown that AE technique does have capability to detect the damage processes of PP fiber reinforced concrete.
