Special formulas of dry building mortars for construction concrete printing is one of the pertinent areas in the development of innovative construction. The research covers the dry building mortar technology with re-dispersible polymeric powders. The best regime of mixing components with a high-speed paddle wheel agitator was presented. It was shown that only the automation of the construction material production for 3D printing will provide the necessary level of composition stability and property optimization. The work presents some methods of technical control in the production environment. According to the devised functions the technical specifications for the material use were developed. The technical and operational characteristics of the obtained material were researched and the advantages of using polymer-cement concrete in construction 3D printing were identified. On the basis of the obtained results it was established that the specifically designed composition of the mortar reduces stiffening time, has good adhesion characteristics and the necessary plastic strength, this material also delivers impressive performance when it comes to strength and other technical and operational characteristics in comparison with the test mortar.
