The following article will guide you about how to determine the liquid limit of soils by applying either of the two methods explained in this article. The methods are: 1. Casagrande's Mechanical Method 2. Cone Penetration Method. 1. Casagrande's Mechanical Method: The mechanical method of determining liquid limit using Casagrande's liquid limit apparatus is also known as the percussion method. [...]
Shrinkage limit can be determined in the laboratory using a disturbed or undisturbed soil sample. Principle for Determining the Shrinkage Limit of Soil: Figure 5.11 shows the schematic diagram in which a fully saturated soil in stage I having volume V1 undergoes shrinkage and on complete drying reaches stage III, where the entire water is evaporated. Between stages I and [...]
The following article will guide you about how to determine the permeability of soil. Constant Head Permeability Test: Permeability of coarse-grained soils having high permeability is determined in the laboratory by the constant head permeability test. The principle of the test is to measure the volume of water flowing through a soil specimen in a given time and determine the [...]
