초록
The use of oyster shells is proposed as a substitute construction material for geotechnical applications. To investigate recycling possibility as a substitute of sand compaction pile (SCP) for oyster shells, the geotechnical characteristics including permeability and shear strength of crushed oyster shell, sand and crushed oyster shell-sand mixted soil. Experimental results show that the crushed oyster shells are lighter than sand in weight, and have similar characteristics on permeability to sand. The results of direct shear test show that the measured value of friction angle
