Abstract
3D printed concrete (3DPC) technology，while contributing to a profound revolution in the construction industry，still faces huge challenges in large-scale applications due to the presence of weak interfacial structures and properties. Herein, an innovative solution for interfacial improvement based on Micro-Region Vibration (MRV) of magnetorheological fluid (MRF) in 3DPC interfaces, has been proposed. Results indicate that cross printed specimens subjected to magnetic field treatment demonstrate 114% increase of interfacial tensile strength, reaching as high as 2.27 MPa, and 36.2% decrease in interfacial porosity as opposed to the control group. Higher MRV frequencies reduced the strengthening effect irrespective of the magnetic particle size. The optimal activation duration, however, was longer for the finer particles than for the coarser ones. The interfacial fusion of cement slurry by MRV mitigates the interfacial defects in 3DPC. This technology presents a novel perspective to address the interfacial issue in 3DPC and holds great potential to surmount the technical bottlenecks and propel the progress of the industry.
