The utilization of industrial wastes and by-products is one of the strategies for lowering the carbon footprint of the cement and concrete industry to reach sustainable construction goals. The criteria for evaluating the utilization of any industrial waste or by-product material as a supplementary material in cement and concrete technology are primarily related to their impact on the mechanical and durability performance of the final product. On the other hand, some industrial wastes may also provide an added value, such as turning concrete into a magnetorheological material with rheological properties that can deliberately be altered by applying an external magnetic field during concreting operations. This study investigates the potential of fayalite slag (FS), the waste iron silicate slag from the copper industry, to create a more cost-effective and sustainable magnetorheological cementitious mixture. The magnetic properties, phase, and oxide compositions of the FS were determined by vibrating sample magnetometry (VSM) test, X-ray diffraction (XRD) analysis, and X-ray fluorescence (XRF) analysis, respectively. The FS was used as a responsive additive in a cementitious mixture at 10% by volume. The magnetorheological properties were assessed by an oscillatory rheometer equipped with a magnetorheological device that can provide a constant or variable magnetic field during the rheometry test. Test results showed that the FS possesses significant magnetic properties, and incorporating the FS allows for the creation of more sustainable and cost-effective cementitious mixtures with magnetorheological properties that can be beneficial in pumping and 3D printing operations with smart control.
