3.6.2. Core Cutter Method (IS: 2720 Part 29)

Try these first

1. 1.

   What is the purpose of the Core Cutter Method?

   Hint

   Think about why density measurement matters in construction.

2. 2.

   Name a type of soil that the Core Cutter Method is particularly useful for.

   Hint

   Consider which soils have adhesive properties.

3. 3.

   What is the Core Cutter Method used to measure?

   • Compressive strength of soils
   • In-situ density of cohesive soils
   • Shear strength of sediments

   Hint

   Think about soil properties important for construction.

4. 4.

   True or False: The Core Cutter Method is accurate for all types of soil.

   • True
   • False

   Hint

   Consider which soils the method is intended for.

5. 5.

   A construction site is preparing for a new building on clay soil. Discuss how many core samples should be taken and why, considering variability and potential issues.

   Hint

   Think about the variability of soil properties in an area.

6. 6.

   You performed the Core Cutter Method and found the extracted sample had a weight of 300 grams and a known volume of 150 cm³. Calculate the density and discuss what that implies for construction.

   Hint

   Remember the formula for density.
