ACOUSTIC EMISSION PARAMETERS OF ALKALI ACTIVATED FLY ASH SPECIMENS WITH HEMP FIBRES UNDER STATIC LOADING
Original language description
This paper deals with the effect of the different amount of hemp fibres added to fine-grained composite based on alkali activated fly ash matrix on the values of acoustic emission signals parameters obtained during the fracture tests. The prisms specimens with nominal dimension 40 x 40 x 160 mm and initial central edge notch were subjected to tests in three-point bending configuration. The four magnetic sensors were placed on each specimen and acoustic emission signals were recorded during the loading. The obtained results indicate that the specimens with hemp fibres exhibit a larger number of acoustic emission events than reference specimens without the fibres. It can be most likely connected to pull-out or break of the hemp fibres. The addition of hemp fibres causes the attenuation of the AE signals and the reduction of the amplitude values.
