Triaxial Testing- Ensuring the Proper Quality in the Soil Samples

Whenever any of the company wants to ensure the optimum quality of the construction as well as longevity of the whole structure the soil has to undergo several kinds of multiple tests so that quality can be verified very easily. Depending on the nature and behaviour of the soil several kinds of load conditions will always vary. So, one of the best qualities which the companies must test in the soil is the strength. For this purpose, the companies must contact the triaxial testing instruments manufacturer so that they can have proper access to several kinds of equipment which will further help in conducting the tests efficiently and effectively.

 

The tri-axial test can be termed as the geotechnical test that is used to test the mechanical properties of the soil. In this particular testing system, the sample of the soil is put under the pressure till the point of shear is achieved. This particular test can be conducted on distributed high-quality soil so that several kinds of qualities for example sheer strength, cohesion and stress can be measured very well. The size of the samples which have been used for testing will also vary from  8mm-100 mm. Companies can also go with the option of conducting the testing on larger sample size as well.

 

This particular concept will always help in preventing the drainage of the specimen and will also measure the pore pressure, permeability and the stiffness about soil as well as other things. Hence, this particular testing can be very effectively utilized to solve all the problems at the time of constructing the dams, tunnel linings and analysis of several other things so that total stress measure can be dealt very well. 

 

 

 Following are the types of tests which are used in this particular test:

 

 -Unconsolidated undrained test: Under this particular test the sample soil is subjected to cell pressure so that there are no issues. The cell pressure can also be applied so that soil increases in terms of pressure.

 

 -Consolidated undrained test: Under this particular test there are some of the variations and the drainage is sometimes permitted during the application. The process will also become constant without any kind of permission.

 

 -Consolidated drained test: This particular test is known as the slow test and in this particular set up the stress is also applied on the soil which is drained. Soil-pressure will always remain constant and excess pressure will be avoided by slowly applying the loading. These kinds of the specimen are tested in the membrane and the little pressure is applied until the point of failure. The basic motive of conducting these kinds of tests is to have proper and accurate readings of the angles of internal friction as well as cohesion in the soil samples.

 

 Nowadays companies also go with the option of utilizing several kinds of software along with equipment to conduct these kinds of tests. Hence, triaxial analysis equipment is very well used to conduct these kinds of tests so that the quality of the soil can be assessed and usability can be determined.
