Abstract: An electromagnetic interference (EMI) resistant cementitious ink comprising a hydraulic cement, calcium carbonate, silica sand, taconite material, and a conductive material. A ratio of the silica sand to the taconite material is 1:1. In some embodiments, the taconite material includes taconite powder and fine taconite aggregate having a ratio of 1:1. In some embodiments, the conductive material includes carbon-based nanoparticles in solution. In further embodiments, the EMI-resistant cementitious ink has a shielding effectiveness in accordance with ASTM D4935-18 of at least 4.0 dB.
