1. Effect of Addition of Admixtures

Try these first

1. 1.

   What is the primary function of stabilizing agents in soil?

   Hint

   Think about their main purpose in construction.

2. 2.

   How does compaction affect soil density?

   Hint

   Consider what happens to air in the soil.

3. 3.

   What is the effect of compaction on soil density?

   • Increases voids
   • Decreases voids
   • No effect

   Hint

   Think about how air occupies space within soil.

4. 4.

   True or False: Shear strength is higher in cohesive soils compacted wet of optimum.

   • True
   • False

   Hint

   Recall the differences in soil structure based on moisture content.

5. 5.

   Analyze a scenario where a construction project encounters increased settlement in clayey soil after adding an admixture. What steps should be taken to assess the soil condition?

   Hint

   Consider factors affecting soil behavior post-admixture addition.

6. 6.

   In a given area, granular soils have shown increased permeability despite compaction. What factors could lead to this outcome?

   Hint

   Reflect on the basic principles of soil behavior.
