| Outline of Final Research Achievements |
This study carried out to establishment the method to evaluate the durability and environmental safety of coal ash mixed material in order to promote the effective utilization.
As a result, we succeeded in finding the temperature and drying time of the wetting and drying test capable of evaluating the durability without causing slaking, established the condition setting considering the strength level. The coal ash mixed material meets the environmental standards value fir soil and revealed that it is stable over the long term. Also, this study proposed an estimation formula to evaluate long-term durability of real ground from laboratory test. And it was able to reproduce the behavior obtained by the wetting and drying test.
