Geotechnical Engineering Lab

Introduction to Laboratory

Geotechnical Engineering Laboratory contributes mainly teaching activities in the Civil Engineering Department. It provides support in a wide range of specialized areas of soil characterization and stability of the soil mass analysis and testing of soil properties to the students.

This includes: Determination of Consistency Limits and Indices, Determination of Specific Gravity (Using Pycnometer), Determination of Field Density of Soil (Sand Replacement Method), Compaction Test (Standard and Modified Proctor Compaction), Permeability Test (Constant and Variable head), Grain Size Analysis (Sieve Analysis), Direct Shear Test, Consolidation Test, Triaxial Compression Test, Unconfined Compression Test.

Course supported includes:

CE 315, CE 436, CE 438
