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. en_US
