Features of polymer-cement composite formation for innovative construction using additive technology

Abstract

The creation of materials for additive technologies and managing their properties depends mainly on a deep and clear understanding of the processes of hydration and structure formation in disperse systems. This study describes the experience of study of composite polymer-cement material for 3D printing products and designs, peculiarities of structure formation of modified polymer-cement dispersions and their particular components. When researching, diffractograms of modified Portl and have been received and the kinetics of hydration process have been studied. The microstructure of composite material was also studied by means of scanning electron microscopy method. It has been proved that solidified polymer cement structure is represented by conglomeration of mutually penetrating mineral and organic constituents. So, crystallized coagulation structure is formed and it strengthens by polymeric componentin defective places of cement stone (pores, cracks), what leads to the formation of a more solid and elastic structure. Main recommendations were formulated and scientifically-grounded and should be taken into account when creating the polymer cement composites for 3D printing.
