For high concentration disposal of fly ash slurry, a detailed investigation of rheological behavior is required. The addition of a surfactant to slurry reduces surface tension, thereby increasing its spreading and wetting properties of solid particles. Thus the requirement of the amount of water, as well as energy during pipeline transportation, is reduced. The present chapter describes in detail the generation of fly ash from a thermal power plant and its stabilization for pipeline transportation. The rheological behavior of fly ash samples is studied in the presence of some natural and synthetic surfactants. A suitable rheological model is used to discuss the relationship between various rheological parameters. The addition of a surfactant may reduce the viscosity of the slurry. Moreover, the role of the surfactant of bottom ash as a viscosity reducing agent is discussed. In addition, the mechanism of interaction between fly ash particles and the surfactant has been discussed.
