Clay sensitivity classification

WebExplanation: Sensitivity is the degree of disturbance due to ‘remoulding’ and the thixotropy is the process of softening of clay due to ‘remoulding’, followed by time-dependent gain in strength. So, it can be said that they are directly proportional to each other. 8. The gain in strength after remoulding is due to______ WebOct 10, 2024 · Clay sensitivity was the ratio of the undrained shear strength in the field to that in the laboratory, for the same soil. According to the sensitivity classification of Das and Sobhan (2014) , the current study soil included low, medium, and high sensitivity clay. To overcome the difficulties presented in extracting samples of sensitive clay ...
