Hydro mechanical behavior of compacted sand bentonite fiber composite for landfill application

Abstract

Generally a compacted sand bentonite mixture is used as a landfill liner material However at low stress desiccation induced moisture variations can affect the reduction in plastic deformability and forms shrinkage cracks which can increase the uncontrolled migration of leachates particularly around the tensile failure Also if the strength of the base material is not enough e g on steep slopes in bottom liners capping systems and landfill stability then the effective operation of the...
