2.2.2. Sieve Analysis

Try these first

1. 1.

   What is sieve analysis?

   Hint

   Think about how we categorize different soil particles.

2. 2.

   What size particles does sieve analysis generally analyze?

   Hint

   Consider the standard size threshold for sieve analysis.

3. 3.

   What is the main purpose of sieve analysis?

   • To classify soil by color
   • To determine particle size distribution
   • To measure soil moisture

   Hint

   Think about what allows engineers to assess soil's physical properties.

4. 4.

   True or False: Sieve analysis is primarily used for fine-grained soils.

   • True
   • False

   Hint

   Consider what type of soil each analysis method is designed for.

5. 5.

   You have a soil sample and perform a sieve analysis resulting in a gradation curve that is mostly flat. What implications does this have for construction?

   Hint

   Consider the behavior of uniform-sized particles under stress.

6. 6.

   Analyze how the gradation of a particular soil can influence its drainage properties. Provide a detailed answer.

   Hint

   Think about the relationship between soil structure and water movement.
