Microstructure of compacted fly ash

Abstract

Compacted fly ash from combustion of bituminous coal in conventional furnaces, despite its macroscopic similarity to non-cohesive soils, should always be evaluated considering moisture content at compaction, as in the case of compacted cohesive soils. The mechanical parameters and hydraulic conductivity of fly ash depend strictly on the moisture content at compaction. However, fly ash differs in structure from cohesive mineral soils. The microstructure studies were performed on samples of fly ash compacted according to the standard Proctor method of optimum water content ± 5%. The various microstructure of fly ash compacted at both sides of optimum water content was determined by means of ESEM image analysis
