Abstract

This research examines the differential interlayer capacity of 3D concrete printed (3DCP) specimens via mechanical characterization procedures, comprising of direct tension test (DTT), Iosipescu shear test (IST), and orthogonal compression tests. The experimental findings are subsequently correlated to cohesive parameters that represent the adhesive capacity of the interfacial transition zone (ITZ). Furthermore, the cohesive parameters are validated via supplementary mesoscale analytical calibration and finite element (FE) analysis procedures. The experimental works conducted are envisioned to take an incremental step towards detailed design specifications that allow for the rational design of load-bearing 3DCP components and structures at a macroscale.
