5.4.3. Aggregate Crushing Value Test (IS 2386 Part IV)

Try these first

1. 1.

   What is the Aggregate Crushing Value (ACV)?

   Hint

   Think about how strong aggregates need to be.

2. 2.

   What is the ideal ACV for aggregates used in roads?

   Hint

   Consider what happens to concrete durability.

3. 3.

   What is the main purpose of the Aggregate Crushing Value Test?

   • To determine the water absorption of aggregates
   • To measure the resistance of aggregates to crushing
   • To assess the grading of aggregates

   Hint

   Think about what the test assesses about the aggregates.

4. 4.

   A lower ACV is preferred in which of the following applications?

   • True
   • False

   Hint

   Consider how strength impacts concrete quality.

5. 5.

   You have two aggregates, one with an ACV of 28% and another with an ACV of 35%. Which one will you choose for a high-strength concrete mix? Why?

   Hint

   Think about how the ACV affects concrete performance.

6. 6.

   Explain how you would conduct the ACV test and what factors might influence the accuracy of your results.

   Hint

   Recall the steps and environmental considerations for accurate testing.
