THEORETICAL JUSTIFICATION FOR THE REGULATION OF STRUCTURE FORMATION PROCESSES OF GAS-FILLED SYSTEMS
The work is devoted to the analysis of the processes of structure formation at the stages of production and operation of gasfilled building materials. Questions of regulation of setting and hardening of gasfilled systems on the example of foam concrete are considered. There are four four phases of structure formation of gasfilled systems: structure formation at the stage of manufacture, the stage of coagulation structure formation, the stage of formation of condensation - crystallization structure, structure formation at the stage of operation. At the stage of production, transportation, molding of products, the gasfilled suspension is a liquid fluid mass having nonlinear, viscoplastic properties. The stage of coagulation structure formation ends with the beginning and end of setting. The third stage of the structure formation of concrete materials is completed by the formation of condensation - crystallization structure of their hardening. The fourth stage is the structure formation in gasfilled building materials at the stage of operation.
