How to fill out liquid limit plastic limit

How to fill out liquid limit plastic limit

1. Start by preparing the soil sample and weighing it accurately.
2. Place the soil sample in the liquid limit device and add water while kneading the soil to form a uniform paste.
3. Allow the soil paste to sit for a specified time to allow for water absorption.
4. Begin the liquid limit test by using a grooving tool to create a groove in the soil paste.
5. Continue to add water and repeat the grooving process until the soil paste begins to flow and close up.
6. Record the number of blows required for the soil paste to close up and calculate the liquid limit value.
7. To determine the plastic limit, continue with the same soil sample and perform the soil paste rolling test.
8. Record the moisture content at which the soil paste crumbles to find the plastic limit value.

Who needs liquid limit plastic limit?

1. Geotechnical engineers and environmental scientists may need liquid limit and plastic limit measurements to assess the soil properties and engineering behavior of soil samples.
2. Construction companies and contractors may also require liquid limit and plastic limit values to determine the suitability of soil for building foundations or road construction.
