Activity Evaluation of Nanostructured Binders with Using Thermodynamic Method

This paper analyzes the process of obtaining nanostructured binder (NB) on the basis of materials of different genetic types. An increase in dispersion of binders aside from their composition during the process of mechanical activation of the solid phase and the formation of fraction in nanosized range was shown. Effectiveness of the thermodynamic method for estimating the energy state of the materials developed by scientists NArFU to predict the formation of active connections and, as a consequence, the binding properties of the studied materials were confirmed. It was shown that the kinetics of the activity in case of silicate NB has a wavelike nature, alternating extremes of system activity in general. Herein minimum of activity coincides with the reloading of solid phase when grinding, however it is noted that the system is ready for transformation. In the case of the aluminosilicate binder an increase in activity occurs continuously and reaches its maximum during grinding for 10–11 hours.
