The purpose of the project is to develop low-carbone multicomponent cements due to the complex combination of complementary highly dispersed components, nano-additives and chemical modifiers of air-entering action in the direction of the formation of modified concrete and building mortars on their basis. The main tasks of the phase are the study of granulometric composition, changes in surface energy and the puzolana activity of SCMs of natural and antropogenic origin of different groups. Method of research. The particle size distribution of supplementary cementing disperse systems was investigated using a laser analyzer Master Sizer 2000. The phase composition and microstructure of ultrafine cement-addition additives, portland cements with ultrafine supplementary cementing materials were determined using X-ray diffraction and thermal analysis methods, electron microscopy.5481 Product Description popup.authors Іващишин Г.
