This paper presents the intensity crack zones of a damaged reinforced concrete (RC) beam with the size of 200 mm x 300 mm x 1500 mm repaired with an epoxy injection under monotonic loading. The acoustic emission (AE) technique concurrent with three-point loading was used to monitor the behaviour of the beam. The intensity analysis based on AE signal strength was carried out on CH6 and CH7 at each crack mode. It was found that the intensity plots are well matched with the progression of the crack in the beam. It is inferred that the intensity zones can be utilised to characterise the damage in the beam.
