Comprehensive Investigation of Composition, Properties and Structural Characteristics of Ash-Slag Mixtures for Their Utilization in Construction Composite Materials
Abstract
The results of studies of chemical and phase compositions, structural features, physico-chemical and physical properties of ash and slag mixtures of boiler stations Amazar, Chernyshevsk Zabaikalsky and Borzya (Zabaikalskaya Railway) are presented. The investigation revealed that the specific effective activity of natural radionuclides ranged from 217 to 306 Bq/kg, which complies with regulatory requirements for the application of these waste materials in road construction applications. It has been established that these mixtures can be effectively utilized as inert porous fillers in composite material formulations. The findings demonstrate that the mineralogical composition and heterogeneous pore space of the fly ash-slag mixtures have the potential to enhance the thermophysical properties of resulting composite materials.
