Eco-Cement for 3D-Additive Technologies in Construction

Modern construction technologies develop mainly through the use of new materials and minor changes in the construction of buildings. This paper presents the advantages of using 3D-additive technologies in construction: increasing the speed of construction, cutting production costs, energy efficiency, sustainable use of secondary construction resources and advanced materials, great variety of space-planning and architectural solutions. This line of research confirms the relevance of the selected problem. Requirements to composite binders with the predefined set of properties and structural and functional organization are specified. The criteria of selecting the composites’ formulas for using them in 3D printing technologies are formulated. The findings of prism strength and energy-efficiency studies of composite binders on the basis of eco-cement are presented. To meet a number of technical, technological and economic requirements to a concrete on the basis of composite binders for 3D-additive technologies in construction, the application of a set of modifying additives and eco-cement is needed.
