Abstract

In this research, effects of pine tree sawdust on geotechnical properties of two types of kaolinite clayey soil was evaluated. So that, sawdust in 3, 6 and 9 percent (by weight) in dry condition randomly mixed with two kaolinite clayey soil with different plasticity index. Compaction, uniaxial, permeability (falling head) and consolidation tests were performed on specimen. Results showed while 3% sawdust mixed to samples, 24% minimum void ratio (emin) decreased in kaolinite clay with high plasticity index. Also, in this condition, increasing of bearing capacity and strength, ductility and decreasing in water absorbing have been happened.
