The introduction of innovative 3D printing technologies in the construction industry makes it possible to increase the efficiency and environmental sustainability of materials. In parallel with the development of this technology, there was a need to create modification mixtures using waste materials. This study examines the use of waste-based modification additives in construction 3D printing technology.
The main physico-mechanical properties and strength of fine-grained concretes formed by the method of layered extrusion show the high efficiency of using a modification mixture in the production of cements, mortars and concretes with a given complex of rheotechnological properties, depending on the composition of raw materials mixtures, interaction conditions and conditions.
In the course of the study, the properties of waste materials are studied and the possibility of their use in the composition of building mixtures used for 3D printing is analyzed. Various experiments were carried out in order to determine the efficiency of waste materials and their effect on the physical and mechanical properties of building materials.
As a result, it was found that waste-based modification additives contribute to increasing the strength, stability and environmental friendliness of building materials in construction 3D printing technology. It aims to provide new opportunities and solutions in the construction sector, considering the environmental benefits and economic benefits of these approaches.
