3.5.5. Los Angeles Abrasion Test (IS: 2386 Part IV)

Try these first

1. 1.

   What does the Los Angeles Abrasion Test measure?

   Hint

   Think about the properties of aggregates.

2. 2.

   What is the acceptable wear loss percentage for high-quality concrete?

   Hint

   Remember the specified limit discussed.

3. 3.

   What property does the Los Angeles Abrasion Test assess?

   • Water resistance
   • Wear resistance
   • Thermal resistance

   Hint

   Consider what the test examines regarding aggregates.

4. 4.

   The acceptable weight loss percentage for aggregates in high-quality concrete is:

   • True
   • False

   Hint

   Recall the specific limit mentioned.

5. 5.

   You are tasked with selecting materials for a new concrete highway. One aggregate type shows a wear loss of 35%. Discuss the implications of using this aggregate based on the Los Angeles Abrasion Test results.

   Hint

   Reflect on the requirements for structural integrity.

6. 6.

   During the Los Angeles Abrasion Test, an aggregate sample showed a weight loss of 15%. How would you justify this result for concrete use?

   Hint

   Consider what this level of wear indicates about the aggregate's performance.
