Question
In a shrinkage limit test, the volume and mass of a dry soil pat are found to be and , respectively. The specific gravity of the soil solids is and the density of water is . The shrinkage limit (in %, up to two decimal places) is ______
Correct answer
19.5 to 20.5
Solution
The shrinkage limit can be calculated using the formula:Given:
Mass of dry soil pat,
Volume of dry soil pat,
Specific gravity of solids,
Density of water, First, calculate the dry density :Now, substitute the values into the shrinkage limit formula:Rounding to two decimal places, the shrinkage limit is .
