The purpose of the work is to develop the technology of low-carbon multicomponent cements due to the complex combination of supplementary cementitious mineral highly dispersed components of natural and technogenic origin, nano and chemical additives, plasticizing-accelerating action in the direction of formation of specified construction and technical properties of modified concrete and building mortars on their basis, while minimizing energy consumption on their production. Research methods. The particle size distribution of supplementary cementitious powder-like disperse systems was investigated using the Mastersizer 3000 laser analyzer. The phase composition and microstructure of cements with high content of SCMs were determined using X-ray diffraction and differential-thermal analysis methods, electron microscopy. Optimization of granulometric and material composition of low-carbon multicomponent cements was carried out by the method of mathematical planning of the experiment. The physical and mechanical properties of low-carbon multicomponent cements were determined in accordance with DSTU B В.2.7-46: 2010 and DSTU B EN 197-1: 2015.
