1) A clay has the following Atterberg limits: Liquid Limit (LL) = 60 Plastic Limit (PL) = 40 Shrinkage Limit (SL) = 25 The clay shrinks from 15 cm3 to 9.57 cm3 when the moisture content is decreased from the LL to the SL in the Atterberg tests. What is the clay’s specific gravity (dry)?
1) A clay has the following Atterberg limits: Liquid Limit (LL) = 60 Plastic Limit (PL)...
Which best describes the Plastic Limit (PL) in the Atterberg Limits? Moisture content where soil changes from plastic to brittle Moisture content where a semi-solid soil stops shrinking and becomes solid Moisture content where soil first has shear strength Moisture content coinciding with the plasticity index

QUESTION 3 A saturated, normally consolidated clay has a water content of 30, a liquid limit of 40, and a plastic limit of 20. The specific gravity of solids in the clay is 2.70. After demolition of an existing building, the effective vertical stress in the clay reduced to half of the prior stress. Most nearly, how much will the void ratio of this clay increase after unloading?
