Abstract
Due to the population growth and development of industry, waste from household and industries has increased. As the advanced countries experienced these problems, they have already started research on recycling methods of waste incineration ashes. Domestic recycling rate of incineration ash became up to 80 percent as high as the level of developed countries, but the recycling was limited to fly ash for admixture in concrete. In case of bottom ash, most of bottom ash was reclaimed in the landfills. Therefore, basic physical property and mechanical experiments for bottom ash were conducted in this study to evaluate the possibility of incineration bottom ash as an alternative construction materials. Bottom ashes from three different landfills with two different incineration methods were tested. Incineration methods are Stoker type Incinerator and Pyrolysis-Melting Treatment. Bottom ash can be used as an alternative granular material for construction based on the basic physical property and mechanical characteristics similar to those of sandy materials. However, the incineration method should be considered since it can affect the material and mechanical characteristics of the incineration bottom ash.
