Abstract:

Waste management is one of the serious problems in India. The advancements in the field of geotechnics and geosynthetic are associated with growing environmental concern and have enabled the switch from open dumps to landfills. The main objective of the impermeable landfill liners is to reduce the migration of leachate to the ground water and reduces the reasonable amount. One of the critical parts of a landfill is liner. Generally, the materials used as liner is clay, but later on crack formation and degradation were observed for clay liners. Thereafter researchers began for obtaining a suitable material for landfill which is strong, least permeable, and also economical. For which an attempt was made to determine a mixture of bentonite and quarry dust as a liner it is a waste product from crusher and satisfies all the criteria of a landfill liner. In this Study the characteristics of mixture are determined with varying percentages of bentonite at 3, 6, 9, 12&15% and 10% quarry dust as liner and finally it was concluded that addition of 15% bentonite clay, behaved as a good barrier for the landfills
