Geotechnical Engineering Lab
Overview
The purpose of the laboratory is to study the various types of tests used for soil testing. Each experiment of soil testing is presented with brief introduction covering the important details of the experiment, the theory and the applications of the same. With the help of these Students can perform and analyze the properties and strength of the soil by using testing machines like direct shear testing machine, consolidation, unconfined, triaxial testing machine, Compaction and relative density. The total area of the lab is 175 sq. Meters.
Laboratory Area: 171 Sq. Mts
Laboratory Expenditure: Rs.7,92,589
