Cyclic Behavior and Liquefaction Potential of Indian Pond Ash Located in Seismic Zones III and IV

Abstract

In the present study, cyclic behavior and liquefaction potential of pond ashes collected from Talcher, Panki, and Panipat ash embankments located in seismic zone III and IV have been studied. Cyclic triaxial tests were conducted on reconstituted pond ash samples at a relative compaction varying from 94 to 99%. The effects of loading frequency, confining pressure, and relative compaction on cyclic behavior and liquefaction potential of reconstituted pond ashes have been studied. From test results, it is seen that all compacted pond ash samples exhibit good liquefaction resistance, dynamic properties, and degradation index. It may be concluded that pond ashes from Talcher, Panki, and Panipat can effectively be used as a geomaterial in geotechnical applications.
