Construction technologies are among the most critical in terms of negative impact on the environment. Burnt binders, primarily cement and air-lime, emit significant volumes of carbon dioxide and man-made heat. At the same time, a large amount of hydrocarbon fuel is also consumed for their firing. Therefore, to achieve sustainable development goals, the development of alternative binder formulations or innovative ways to produce traditional binders with low carbon emissions is necessary. The synthesis of low-carbon binder compositions that provide the required properties is based on the use of mineral or organomineral compositions with the use of highly dispersed fillers or modifiers. Technogenic resources are used as such fillers, including those extracted by the fuel industry – REA-gypsum, fly ash, bottom ash and their individual components. Recently, interest in aluminosilicate microspheres has been growing. They are isolated from ash and slag waste from coal power plants. When they are removed hydraulically, the calcium content in the waste decreases due to its fairly high solubility. The paper presents the results of a study of the physical and mechanical properties of cementless compositions for additive technologies based on aluminosilicate microspheres. Microspheres have a number of unique properties.
The synergistic effect is achieved by combining a self-reinforced matrix, which ensures the stability of the mixture during the process of stone formation with a rapid increase in strength with the participation of microspheres, necessary when using compositions in additive technologies.
