EVALUATION OF LIQUEFACTION POTENTIAL OF POND ASH
Pond ash (fly ash) obtained from thermal power plants or similar plants which use the coal as a fuel, has spread over a large area of land in the country like India. A challenging task is to improve these areas for further construction of civil engineering structures like buildings, roads etc. Keeping this in view the studies on pond ash have been taken up. Pond ash is a very fine, non-plastic and loose material dumped over the ground usually for a height of 10 to 30 m. Such types of materials are normally susceptible to liquefaction.The aim of this paper is to study the liquefaction behavior of pond ash obtained from a particular thermal power plant of India. The samples of pond ash obtained from top 5 m were prepared at a relative density of 20%. The tests were conducted on small Shake Table in the laboratory at different accelerations varying from 0.1g to 0.5g, keeping the frequency of dynamic load constant. The liquefaction resistance was determined in terms of pore water pressure ratio (ru). The liquefaction resistance is also determined based on the data collected from the field tests.
