1.4. Select the Cement Content

Try these first

1. 1.

   What is the ideal cement percentage range when modifying subgrade?

   Hint

   Look for the specific percentage mentioned in stabilization discussions.

2. 2.

   Name one test used to determine maximum dry unit weight.

   Hint

   This test's name includes 'Proctor'.

3. 3.

   What is the recommended cement content for modifying subgrade?

   • 2%
   • 4% ± 0.50%
   • 6%

   Hint

   Reference the cement content mentioned.

4. 4.

   True or False: The unconfined compression test is not necessary for cement stabilization.

   • True
   • False

   Hint

   Think about the importance of testing.

5. 5.

   Given a soil has a dry weight of 2000 kg, what is the amount of cement you would typically add for stabilization?

   Hint

   Use the percentage directly on the dry weight.

6. 6.

   How would you plan a quality control system for a project including cement stabilization? Outline your steps.

   Hint

   Think through the entire process from testing to adjustment.
