Abstract

The article presents a set of experimental-static models of the properties of fine-grained concretes on a cement–slag binder and quartz sand with the addition of a hardening accelerator made on a 3D printer. The influence of the factors of the composition of the mixture and the effects of their interaction on the studied properties of concrete was established. By analyzing the models, the influence of the factors of mixture composition on the studied properties was ranked. The nature and degree of interrelation of individual properties of concrete are shown. The relationships between structural strength and setting time, as well as various strength indicators of concrete produced on a 3D printer, were established for different values of mixture composition factors.

The use of a binder containing 30… 40% of ground-granulated blast-furnace slag and of hardening accelerator–sodium sulfate in the amount of 1…2% by weight of the binder allows obtaining energy-efficient mixtures suitable for 3D printing.
