Microstructure of compacted transitional soil
Microstructure of compacted transitional soil
Fly ash and non-plastic silt are transitional soils that macroscopically resemble non-cohesive soils. However, their characteristics after compaction strictly depend on water content at compaction, as in the case of cohesive soils. Therefore, water content at compaction should always be considered in geotechnical analyses of these soils. The study aimed to investigate the microstructure of fly ash samples compacted by the Standard Proctor method at optimum water content ± 5%. The fly ash samples were qualitatively evaluated by an environmental scanning electron microscope (ESEM). Afterward, ESEM images and their computer analysis were used to define the pore structure and pore size distribution of the compacted fly ash.
