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.

3D printable cementitious ink including electromagnetic pulse resistant binders

A 3D printable clay-based mortar cementitious ink includes a blend of commercially available Portland cement, calcium carbonate, sand, and calcined clay. The calcined clay is produced from the calcination of clay having a high kaolinite content of greater than about 60%. The clay is calcined at a temperature of between about 600° C. and about 800° C., preferably between about 650° C. and about 850° C., for a period of one to two hours. In a preferred embodiment, a ratio of calcined clay to Portland cement is about 0.148, a ratio of calcium carbonate to Portland cement is about 0.333, and a ratio of sand to Portland cement is approximately about 3.0. The ratio of water to powder (clay, cement, calcium carbonate, and sand) may range between 0.39 and 0.40.

3D printable portland limestone clay-based mortar utilizing locally available materials

Systems and methods for preparing a three-dimensional printing material derived from aluminosilicate material are provided. The method includes the steps of heating an amount of aluminosilicate powder to a temperature between approximately 1,100° C. and approximately 1,750° C. to form a molten aluminosilicate material; maintaining the molten aluminosilicate material at a temperature between approximately 1,100° C. and approximately 1,750° C. between about one minute and approximately 45 minutes; extruding molten aluminosilicate material through a nozzle to form an elongated bead of molten aluminosilicate material; and cooling the molten aluminosilicate material to form a hardened aluminosilicate material. Once hardened, the aluminosilicate material includes between about 50% and 90% feldspar and demonstrates a strength of between about 5,000 psi and 30,000 psi. The systems and methods enable the construction of structures using raw, in-situ natural resources without the need for additives to adjust or modify the viscosity of the molten material prior to extrusion or printing.
