Measurement of Liquid and Plastic Limits by Fall Cone Test

Consistency limits are often used as an index to show the properties of cohesive soils. In spite of its usefullness， the conventional method of measurement of consistency limits has many disadvantages such as the human effects，the difficulty of standardizing the measuring devices，etc. This investigatigation is an attempt to eliminate these defects by using the fall cone test. In this paper，experimental results and subsequent discussions of the fan cone test to measure liquid and plastic limits are presented. Also in this study，it is found that liquid and plastic limits are both measurable with one series of fall cone tests using improved techniques
