Few days ago, a Regional QAQC Manager was having a discussion with his fellow subordinates in regards to Atterberg liquid and plastic limit of soil samples. I was there to pass some documentation and he then popped out the question; "why do we roll the soil samples into 3.2mm or 1/8 inch diameter until it breaks into chunks?" There are so many journals out there which give in-depth explanations to this event but it is hard to understand, therefore i simplified it as follows; Similar to steel, soil do have their modulus of elasticity properties and defined using Young's Modulus value. Soil also have its own shrinkage limit, similar to concrete. |
