Geotechnical Engineering Testing: Which Test Cannot Be Performed Using Samples from a Standard Split-Spoon Sampler?

Which of the following tests cannot be performed using samples from a standard split-spoon sampler?

a. Unconfined compression test
b. Moisture Content test
c. Gradation analysis test
d. Atterberg limits test

Answer:

The sample collected from a standard split-spoon sampler cannot be used in the Unconfined compression test.

Geotechnical engineering involves testing soil samples to determine various properties of the soil. One of the tools used to collect soil samples is a standard split-spoon sampler. While samples collected from this tool can be used in tests such as moisture content, gradation analysis, and Atterberg limits, they cannot be used in the unconfined compression test.

The unconfined compression test is used to determine the compressive strength of the soil. Since samples collected from a standard split-spoon sampler may not provide an accurate representation of the soil's compressive strength, they are not suitable for this particular test.

It is important to understand the limitations of different testing methods and ensure that the appropriate sampling tools are used to obtain reliable data for geotechnical engineering projects.
