Liquid Limit Test Utilizing Casagrande Apparatus Liquid limit test utilizing Cone Penetrometer apparatusĪ. Liquid limit test utilizing Casagrande apparatusī.
There are two ways of determining the liquid limit of soil. To get the information on fine-grain soil (cohesive soil) about the consolidation properties. “Liquid limit of soil is the minimum water content at which a pat of soil cut by a groove of standard dimension will flow together for a distance of 12 mm under an impact of 25 blows in the apparatus(either Casagrande or Cone Penetrometer.).”Ī.
The liquid limit of soil is the minimum water content at which the soil is still in the liquid state but has a small shearing strength against the flow.įrom the test point of view, the liquid limit of soil can be defined as: A liquid limit test of soil is done to get the information on fine-grain soil (cohesive soil) about the consolidation properties of soil while calculating allowable bearing capacity & settlement of the foundation.
