Influence of Curing on Acoustic Emission Characteristics of Plain Concrete Subjected to Uniaxial Compression

Priyadarshi, Richa / Narsaria, Isha / Sreejaya, K. P. / Vidya Sagar, R.

Abstract Acoustic emissions (AE) released during the uniaxial compression testing of cylindrical plain concrete specimens were analysed to study the fracture process by the computation of b-value of Gutenberg–Richter relation. Also, the influence of curing of plain concrete on AE characteristics like energy and cumulative count has been studied. The b-value decreased suddenly at ~96% of failure stress. Also, the lateral shift towards left was observed in b-value based on the concrete compressive strength. The cumulative AE count at different stages of loading can be useful to study the crack propagation. Also, the crack pattern emerged on the test specimen near the peak stress was analysed using the locations of the AE events recorded. At the time of ultimate failure, shear cracks were observed.
