Study of Ash-Slag Wastes of Electric Power Plants of Mongolia Applied to their Utilization in Road Construction

Abstract

AbstractThe results of a study of ash-slag wastes generated by Erdenet and Darkhan Electric Power Plants (Mongolia) by means of Scan Electron Microscopy with X-ray microanalysis and X-ray powder diffraction are presented. Both types of the ash-slag waste have acid, highly carbonaceous, poor calcium composition that implies their insufficient cementing properties. It is recommended to dope this ash-slag with cement or lime (limestone) utilized as an ash-soil concrete in the road construction
