Abstract
This work discusses the development of concrete mix compositions using modifying additives, the study of the rheological and strength properties of compositions for construction 3D printing. Cellulose ether (CE), calcium formate (CF), and redispersible polymer powder (RPP) were studied as modifying additives at different percentages by weight of cement. Compression strength tests have shown the most promising compositions for their further study for rheological parameters. The best strength indicators in the early and late periods of hardening were shown by the composition with the introduction of 2% RPP and the composition with 2% CF. The composition with 2% RPP has an increased density and viscosity and relatively low flowability, and also has a shortened setting time, which makes the use of an RPP additive effective for additive construction methods.
