Unsaturated Hydraulic Conductivity Behavior of Bagasse Ash Treated Tropical Black Clay
A laboratory investigation was carried out on tropical black clay (an expansive soil also known as black cotton soil because cotton plant thrives well on it) treated with up to 12% bagasse ash by dry weight of soil. Specimens were prepared at optimum moisture content and compacted using British Standard light or Standard Proctor (relative compaction = 100%) to evaluate its effectiveness when used in waste containment application. Soil-bagasse ash mixtures were assessed to determine their soil water retention behaviors by curve fitting methods using the two most common soil water characteristics curve (SWCC) models, developed by van Genuchten and Brooks - Corey. The unsaturated hydraulic conductivity values decreased with higher bagasse ash content and matric suction but were less than 1 x 10-9 m/s required for a liner material.
