Hardened fracture characteristics of printed concrete using acoustic emission monitoring technique
J.G. Yue*, D.E. Beskos, C. Feng, K. Wu
ABSTRACT：
This paper presents a study on the fracture behavior of hardened printed concrete. The fracture properties of conventional cast and printed concrete (in three printing types) were compared by conducting the splitting and three-point bending tests. The anisotropic behavior of printed concrete was analyzed through the micro-cracking mechanism monitored by using the acoustic emission (AE) technique. Compared to the cast concrete, the fracture strength of printed concrete is reduced, especially when the load was applied at the interface between the successively printed filaments. The interfaces affect the micro-cracking modes during the fracture process of the printed concrete. When the number of shear micro-cracks increases, the values of splitting strength, flexural strength and fracture energy decrease. Useful criterial indicators for the design of a printed concrete member or a structure are suggested.
