Abstract

The article shows the possibility of obtaining cement-slag fine-grained concrete mixtures and concretes, which can be used as working mixtures for a 3D printer. The resulting complex of experimental and statistical models makes it possible to predict the influence of factors characterizing the composition of the mixture on the main properties of concretes intended for 3D concreting. The developed compositions of mixtures make it possible to provide the required values of the setting time, structural strength, splitting and compressive strength at an early and projected age. The influence of granulated blast-furnace slag and the addition of a hardening accelerator on the complex of properties of the proposed fine-grained concrete for 3D concreting has been established. With the use of mathematical programming, implemented by the Microsoft Excel software environment and its application "Search for a solution", the possibility of solving the problem of designing optimal compositions of building mixtures suitable for 3D printing is shown.
