DataFrame.geotech.lab.index()#

Subaccessor that contains methods related to index property tests.

The index properties of soil are the properties which help to assess the engineering behavior of soil and determine the classification of soil accurately.

Notes

The index properties of soil are important for understanding the physical and chemical characteristics of soil. They are used to classify soil and predict its behavior under different conditions. These properties are determined through laboratory tests, some key properties include:

  • moisture content [1]

  • consistency or Atterberg limits [2]

  • particle size distribution

  • specific gravity

  • soil classification
