The Plastic Limit Test Set is used to determine the plastic limit of fine-grained soils, which is the lowest moisture content at which soil remains plastic. This parameter is crucial for soil classification and assessing the behavior of soils under varying moisture conditions.
The test involves rolling a soil sample into threads of 3 mm diameter. The moisture content at which the threads begin to crumble indicates the plastic limit. This method provides a simple yet effective means to evaluate soil consistency.
The set includes a glass plate providing a non-porous surface for rolling, a stainless steel rod to verify thread diameter, moisture tins for sample storage, an evaporating dish for mixing, and a spatula for handling samples.
Compliant with international standards, the Plastic Limit Test Set ensures accurate and repeatable results, making it suitable for geotechnical laboratories and field testing.
When used alongside the Liquid Limit Test, this set facilitates the determination of the Plasticity Index, a vital parameter for evaluating soil plasticity and workability.
