The Technogenic Raw Materials Surface Characteristics Role when Obtaining the Autoclave Hardening Binders of

Abstract:

The paper investigates the surface wet magnetic separation (WMS) technogenic raw materials concentration tailings particles properties. The mechanical activation effect nature on the binder structural and phase characteristics is revealed. High pozzolan activity of WMC tails, which consists in genetic and morphological features of the surface of poly-mineral structures has been established. During mechanical activation of lime together with WMS tailings, an increase in the number of neoplasms occurs in the amorphous phase form with a low degree of polymerization, which is confirmed by the acid-soluble SiO₂presence, as well as by X-ray phase analysis. The work results indicate a WMC waste particles surface high energy potential for its use in building materials for autoclaved hardening. This study will contribute to the energy and resource-saving technologies development, the solution of environmental problems in order to create a comfortable environment for life and work.
