Concrete mixture grout for printing extruder
The method of full or partial automation of masonry of stone structures has great prospects. A big hindrance to the development of 3D technology in construction is the need to adapt the concrete mixture to the narrow aperture of the nozzle of the extrusion die. In additive manufacturing, known as 3D printing, properties such as the static and dynamic yield stresses of jointing materials play a main role. The purpose of this article is to define the most optimal concrete mix solution for a printing extruder, which will have the highest rheological indices. In the article was considered the scheme of solution feeding system. The optimum percentage relationship of raw materials included in the watercement solution for further feeding through the nozzle was calculated. The static yield strength of the concrete mixture exceeds 5000 Pa, and the dynamic - above 250 Pa.
