WebHere, the cohesion increased by approximately 5900% and 3100% for silty clay and sand, respectively, comparing the samples at the temperatures of −1 °C and −10 °C. Similar to the cohesion, the reduction in temperature from −1 °C to −10 °C led to an 11.1% and 8.4% increase in the internal friction angle of silty clay and sand ... WebOct 10, 2024 · The dry density increase led to additional inter-cohesion between clay particles. Consequently, the increment of liquid limit, plasticity, and consistency indexes was an indication of the high values of clay contents in the studied sensitive soil. The higher value of clay contents caused higher values of cohesion (undrained shear strength).
