초록
The objective of this study is to find the electrical properties of Bottom ash from thermoelectric power plants in Korea. By usingParallel Plate Method, the electrical resistivity and dielectric constant were measured at the frequency from 20 Hz to 10 MHz. Also,unconfined strength test, XRF and sieve analysis were performed for finding the relationship between strength, physiochemical propertiesand electrical properties. In the result, the change of electrical resistivity and dielectric constant of bottom ash against frequency wassimilar to that of general soil. The proportion of fine grain in bottom ash had the positive correlation with dielectric constant andnegative correlation with electrical resistivity. Chloride and sulfur trioxide were proportional to dielectric constant and the more bottomash had chloride content, the lower electrical resistivity appeared in bottom ash. Unconfined strength of bottom ashes had a rangefrom 200 kPa to 780 kPa and strength was inverse proportional to electrical resistivity.
