ABSTRACT
Problem statement. Key problems of rheology at the physical stage of concrete structure formation are considered. Results and conclusions. Connection between behavior of dry and wet granular systems and their fractal structure is discussed. Fundamental features of density relaxation of dry granular systems as well as the loss of their stability under internal surface wetting are examined. The main factors influencing the rheological properties of concrete mixes are determined. The methods of management of kinetics and concrete structure formation directions are suggested.
