Abstract: A 3D printable clay-based mortar cementitious ink includes a blend of commercially available Type I/II Portland cement, and a fine and coarse silica sand. The ratio of Portland cement to fine sand or fine clay, may be approximately 1.02. The ratio of water-to-binder (Portland cement and SCM) may be approximately 0.55, and the ratio of water-to-powder (binder plus fine clay smaller than 75 microns) can be approximately 0.416. Included with the water and binder/powder mix is an admixture. According to one embodiment, the admixture can include a water reducing admixture, or plasticizer. The fine clay within the aggregate material is unprocessed, and the binder material is approximately 84 to 90 percent cement and 10 to 16 percent SCM. The unprocessed clay, or fine sand, does not undergo any heating, any chemical modification or sifting before being added to the aggregate material.
