Solid waste-based set-on-demand 3D printed concrete: Active rheological control of cement-based magneto-rheological fluids

Highlights Solid waste-based magnetic response particles. Active control of rheological properties. Rheological properties are linearly related to additional energy.
Abstract Interventions at the print head, such as magnetic fields, are expected to efficiently improve the buildability of 3D printed concrete (3DPC) without compromising flowability. A cement-based magneto-rheological (MR) fluid material has been developed using electric arc furnace slag powder (EAFSP). This paper found that the storage modulus and dynamic yield stress of cement-based MR fluids dramatically increased with the magnetic field strength and EAFSP concentration. According to the linear fitting results, the rheological properties correlate with the additional energy the magnetic moment obtains whenever a constant magnetic field is applied. Furthermore, after a time-limited magnetic sweep, the 3DPC buildability was improved, probably due to the presence of residual chain-like structures. This research assumes significance for the application of set-on-demand 3DPC.
