4 cards from this section. Quick, good the night before a test.
What is the unconfined compression strength?
Think about how strong the soil can be when there’s no pressure around it.
Why is it important to measure unconfined compression strength?
Remember when we talked about foundations!
What is the value of the minor principal total stress in an unconfined compression test?
Recall that ‘unconfined’ means no pressure surrounding the specimen.
True or False: Unconfined compression strength is an indicator of a soil's ability to support structures.
Think back to the importance of unconfined compression tests in construction.
You have a clay soil sample with an unconfined compression strength of 150 kPa. After testing, you find a moisture increase. Predict how its strength may change, providing reasoning.
Consider the inverse relationship learned in class.
Explain how performing an unconfined compression test could create differing outcomes in saturated versus unsaturated soils, using specific examples.
Recall our discussions about moisture effects on load-bearing capacity.
