Abstract

In this study, an attempt has been made to compare the quality of different filter materials used for dam filters available in different districts of Kashmir Valley of Jammu and Kashmir, India. In order to access the cementation potential/quality of the filter materials the filter materials must undergo strict and accurate composition analysis to improve the filter performance. The amounts of chemical constituents like SiO2, Al2O3, Fe2O3, CaO, alkalies, and loss on ignition (LOI) were determined in accordance with standard procedures and specifications. The performance of filter materials for embankment dams dependent the characteristics like high silica content, low loss on ignition and ferric oxide of the filter material; therefore, the performance depends on the source of the material. The samples from Ganderbal were found to be the most feasible materials for dam filter application because of their high silica content, low loss on ignition and ferric oxide. Due to poor silica content, significant loss on ignition, and ferric oxide, the Budgam sample should be avoided. Thus, it is envisaged that this study will improve the understanding for the selection of more durable and reliable filter materials used in embankment dams in Kashmir valley of Jammu and Kashmir.
