1.2. Procedures for Lime Stabilization

Try these first

1. 1.

   What does lime stabilization aim to improve in soils?

   Hint

   Think about the properties of soil.

2. 2.

   What is a key test performed after lime is added to the soil?

   Hint

   It's how we assess acidity or alkalinity.

3. 3.

   What is the main component used for stabilization in soils?

   • Cement
   • Lime
   • Sand
   • Gravel

   Hint

   It’s a common material in civil engineering.

4. 4.

   True or False: Stabilized soil should always have a pH above 12.4.

   • True
   • False

   Hint

   Think about the goals of lime treatment.

5. 5.

   If a soil sample requires a pH of 12.4 for stabilization, and the current pH is 11.5 with an addition of 5% lime raising it to 12.0, how can we determine the next steps?

   Hint

   What do past experiments suggest about lime's effects?

6. 6.

   Discuss how different clay mineralogies might affect the outcomes of lime stabilization, providing examples.

   Hint

   Think about the chemical compositions of clays and their textures.
