| Research Abstract |
The following results of the research were able to be achieved from this research.
1)The soil mechanics characteristic of bottom ash which contained gravel with the most rates that disposal of reclamation in general waste it is done was clarified. And the geotechnical numerical analysis became possible intended for the disposal of general waste reclamation by using this mechanics characteristics.
2)The unconfined compression strength of about 10kpa was given by self hardening property of the coal ash when the coal ash is added to the incineration ash by 20% compared with weight. In addition, even if it take longer cure than a year, the strength is increasing of the strength, with increasing of the cure period.
3)Lead becomes a problem easily as a toxic material of bottom ash. The elution mount of lead decreases oppositely at 10% or more though the mount increases at 10% or less in the mixing amount of coal ash. Here is not lead alone but no ilution of the heavy metal at the addition amount 20% at all.
