Atterberg limits

Two tests are available in our soil software to determine the liquid limit, namely:

• Liquid limit by the Casagrande cup;
• Liquid limit by the cone penetrometer;

With our soil software "CiviLab", you can easily analyze the results of this test and classify the soil using the Casagrande plasticity chart in record time. CiviLab also produces high-quality reports and archives them properly

For the Casagrande cup liquid limit, CiviLab applies the following standards:

• ASTM D4318-17E01;
• NF P94-051;
• BS 1377-2:2022;

For the cone penetrometer liquid limit, CiviLab applies the following standards:

• NA 16213;
• NF P94-052-1;
• BS 1377-2:2022;

With CiviLab you can:

• Plot water content versus number of blows (Casagrande cup liquid limit);
• Plot water content versus penetration (cone penetrometer liquid limit);
• Calculate the liquid limit W_L;
• Display the plastic limit W_P;
• Calculate the plasticity index P_I;
• Classify the soil using the following charts:
  • Casagrande; 1948;
  • BS 5930:2015;
  • ASTM D 2487-17
