Laboratory Testing Soil

 

Also known as a gradation test, this method determines the distribution of particle sizes within a soil sample by separating it into different size fractions using a series of sieves with varying mesh sizes. 

Function: To evaluate soil gradation and classify soil based on particle size distribution for engineering and geological applications.

 

This instrument is used in soil mechanics to determine the particle size distribution of fine grained soils that cannot be effectively analyzed by sieve analysis. It relies on the principle of sedimentation, measuring how quickly soil particles settle in a water suspension. 

Function: To determine the proportion of different particle sizes in fine-grained soils for classification and engineering analysis.
