Abstract
In this study, the aim is to investigate the damage evolution and crack formation within the layers of 3D-printed Ultra High-Performance Concrete (3DP-UHPC) prisms using Acoustic Emission (AE) testing. The specimens under examination include 3DP-UHPC prisms with and without coarse aggregate, tested in both lateral and perpendicular orientations relative to the printing direction. Micro steel fibers with a volume fraction of 2% are incorporated into the 3D-printed UHPC specimens to enhance the structural properties. The analysis focuses on various AE parameters such as count, duration, amplitude, and RA value (rise time to amplitude). By evaluating these parameters, the study aims to understand how they change throughout the damage progression. Notably, the influence of the direction of printing on the AE activity is also considered, indicating the potential anisotropic behavior of the 3DP-UHPC specimens.
