Abstract:
In order to understand the influence of the disturbance during setting and hardening period on concrete damage,
the simulated disturbance test was carried out on the concrete in the initial setting stage to the final setting stage, and the
acoustic emission signals generated during the compression failure process of the disturbed concrete were collected.
