Controlled-stress, consolidated-undrained triaxial tests with pore pressure measurements were performed on partly saturated bentonite specimens prepared by two different methods of compaction, static and kneading, to give different structural arrangement of the sail particles. The results indicate that the static method employing higher compaction pressure tends to align particles in a more horizontal array as a result of the larger shear strains induced. Samples prepared by the same method of kneading compaction but using different compactive effort of twenty and ten blows with a 20-pound tamper on each of the five layers designated 20-20-5 and 10-20-5 samples respectively show that the less dense 10-20-5 samples have a higher pore pressure response than the 20-20-5 samples as predicted.
