Abstract
Bottom granulated ash is discharged by all incineration plants for municipal waste and is buried at disposal sites as general solid waste. It is important to make use of these sites. However, the mechanical properties of bottom ash have not been well understood. The particle properties of typical bottom ash were observed with a scanning type electron microscope in the study. Various tests including the compaction test isotopic consolidation test, drain triaxial compression test and undrained triaxial compression test were conducted on bottom ash. As a result, the particle shape characteristics of bottom ash, the partide breakage property, critical state line, coefficient of earth pressure at rest, stress-strain behavior and dilatancy characteristics of the materials are presented.
