The manufacturers and builders never carry on with their tasks before they are sure about the material they use. You know, since soil is extensively used in formation of many materials or for the procedures; it is crucial to evaluate the worth of the soil. Here, the shear strength of a soil means its maximum resistance to clipping stresses.

You can easily evaluate the soil with Direct shear equipment and ensure that you have the best results. Of course, testing is crucial in the present time because if you end up with any ineffective outcomes, that can be dangerous for the overall projects.

Using the test

Once you use the direct shear test, you can easily find out the cohesion and angle of internal friction of the soil that are useful in many engineering designs such as foundations, retaining walls,  and so on. Once you are sure about this aspect of the soil, you can proceed for the consequent tasks in a proper manner.

However, you must know that this is a test that can be performed in three different drainage situations namely unconsolidated-undrained, consolidated-undrained, and even consolidated-drained conditions. In general, cohesionless soils get tested for direct shear in any sort of consolidated drained condition.

Observations and Calculations for your Direct Shear Test

You should do the calculations by using the observations you take from the test as follows:

• Mass of specimen =
• Area of the box =
• Size of the box
• Thickness of specimen =
• Volume of specimen =
• Void ratio =
• Bulk Density of soil =
• Dry density of soil =

The point is you need to carry out different calculations before you end up with any sort of outcomes. Moreover, calculations regarding the test should be proper and perfect because everything would rely on that.

What is the Objective of this Test?

For any sort of Cohesion (C) and Angle of Internal Friction (Ø) are two crucial engineering properties, that show the shear strength of soil. These two parameters are needed for design of slopes, calculation bearing capacity of any sort of strata, calculation of consolidation parameters and even in many other analyses. Direct shear test is extensively used to predict these parameters quickly, it is mainly in cohesionless soils.

Choose the Suppliers

You know, the results of your tests or efforts would not be good if you are not using quality tools or equipment. When you look for direct shear machine, make sure that it is of high quality and is useful for your specific tasks. You must choose the right suppliers because you would not want that your results go for a toss because of the wrong selection of the suppliers.

Once you have the right suppliers to get you all the tools you want, you can be sure that they listen to you and then get you the tools that work perfect for your specific sort of tasks. Of course, these suppliers do know what exactly is good for a specific project and which type of test would get the best evaluation.

Conclusion

So, machines and testing is important for your project and you must not take it lightly. After all, if you are not sure about your material or soil before you start your tasks; you cannot perform your manufacturing or other tasks with peace.
