Analysis of Chemical Composition and Physical and Mechanical Properties of Power Plant Ash for its Further Processing

Abstract

The results of the study of ash of Tomsk Power Plant 2 (Toms, Russia) are represented. The grain size composition of ash and distribution of main oxides among fractions have been determined. Physical and mechanical properties and quality indices of ash have been investigated. It has been established that ash of Tomsk Power Plant 2 is referred to a latent active group of cindery waste and can be used as a binding material, in fly ash aggregate productions and in highway engineering

Sulfur-Containing Composite Material for the Concrete Production

“…It depends on the mineral composition and the quality of coal fuel, the construction of furnaces and their working conditions (steam load, the uniformity and temperature of fuel burning in the combustion chamber), the supplying the coal dust for combustion [7]. In this paper, the size distribution of ash particles was determined by sieve analysis in accordance with GOST 9758-77 [8]. The results are presented in Fig.…”

“…The increase in aggregate density of the fine fractions of fly ash is due to the fluctuations of the content of the magnetic fraction. It is because of the fact that the more content of magnetic components, the higher density of the aggregate [8].…”
