Dry cementitious material mixture for 3d-printing

Abstract

A dry cementitious material mixture for 3D-printing, includes a hydraulic cement, a mineral component having a BET-specific surface area of 0.5-30 m2/g, and being present in an amount of 3-50% by weight based on the hydraulic cement, an additional material being one of: at least one viscosity enhancing admixture being present in an amount of 0.01-1.5% by weight based on the hydraulic cement, clay being present in an amount of 0.01-5.0% by weight based on the hydraulic cement, and further optionally comprising aggregates.
