dc.description.abstract |
The lowest permeability and highest shear strength are desirable
factors when designing a liner system. Adding additives such as coal or mixing with
fine clays such as kaolin was also invented to improve the desirable properties of the
liner. The fundamental soil experiments and tri axial tests were carried to determine
the properties of original and mixed clay types. After analyzing, the particle size
distributions of clay types, the mixing compositions of additive materials were
determined. The compacted mixed clay samples of Bricks and Tile clays from
Intermediate zone with kaolin clay to the 70:30 composition gave lowest
permeability as 4.591 * 1008 cm/s. The friction angle is important when determining
shear strength of liner.The internal friction angle that was improved by adding
finely powdered roof tiles (from 12° 10' 8" to 17° 54' 14"). The cohesion between clay
particles that was increased by adding lime (from 51.56 Kpa to 54.23 Kpa). Local
abandoned clay can be improved as a liner materials. |
