Standard CAN/BNQ 2501-090
Soils - Determination of Liquid Limit by the Casagrande Apparatus and Determination of Plastic Limit

This national standard specifies the method used to determine the liquid and plastic limits of soils, from which the plasticity index is calculated. It sets out test method requirements for five main elements:

  • apparatus (sieve, rubber paddle, mortar and pestle, bowl, spatula, liquid limit apparatus, slotting tool, running surface, and other apparatus);
  • preparing the sample (preparing cohesive soils visibly free of any particles larger than 400 µm, cohesive soils containing particles larger than 400 µm and cohesionless soils containing particles smaller than 400 µm);
  • procedures (determining the liquid and plastic limits);
  • calculating and expressing the results (liquid limit, plastic limit and plasticity index);
  • test report.
