• 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.
