Rheometry is essential for the feasibility of 3D printing (3DP) in construction, influencing the extrudability and stability of mortars. This study investigates low-carbon mortars formulated with mining by-products as an alternative to Portland cement. Four formulations were analyzed using a rotational rheometer to assess parameters such as yield stress and thixotropy. The results indicate that the mortar containing 50% ground granulated blast furnace slag and 50% mining waste exhibited rheological behavior closest to the cementitious reference mortar, i.e., rheological behavior suitable for 3DP, thus demonstrating its potential for 3DP applications. The study reinforces the feasibility of using industrial waste in low-carbon formulations, promoting a low environment impact alternative for construction.
