Enhancing Landfill Liner Efficiency: Investigating the Potential of Fly Ash-Bentonite Composite Material
In recent years, a lot of attention has been paid to the use of bentonite and fly ash as liners for landfills. The construction of an efficient liner system is essential to the prevention of contaminants from leaching into the surrounding environment because landfills play a crucial role in the management of solid waste. Based on their index properties, this study focuses on determining whether fly ash and bentonite could be used as composite materials for the development of landfill liner. Fly ash and bentonite’s index properties—physicochemical and Atterberg limits is examined in the present study. Fly ash, a byproduct of power plant coal combustion, has pozzolanic properties that can improve soil’s geotechnical properties. Bentonite is an excellent material for barrier systems due to its low hydraulic conductivity, which makes it a highly swelling clay. The study’s findings show that landfill liner applications with fly ash and bentonite together have promising potential. The Atterberg limits test demonstrates that the composite material's plasticity and workability are enhanced when bentonite is added to fly ash. When compared to fly ash alone, the mixture's compaction properties also show a significant increase in maximum dry density and a decrease in optimal moisture content. Based on the index properties analyzed in this study, the use of fly ash and bentonite as a composite material for landfill liners holds great promise. These materials can effectively contain landfill leachate because of their improved compaction characteristics and enhanced geotechnical properties. To confirm the suitability of this composite liner system for use in actual applications, it is suggested that additional research be conducted on mechanical behavior, leachate compatibility, and long-term durability.
