3.5.3. Aggregate Crushing Value (IS: 2386 Part IV)

Try these first

1. 1.

   What does the Aggregate Crushing Value test measure?

   Hint

   Think about how aggregates behave under weight.

2. 2.

   What is the maximum ACV limit for aggregates used in concrete for roads?

   Hint

   Recall the specific limits discussed.

3. 3.

   What is the acceptable limit for Aggregate Crushing Value for concrete used in roads?

   • Less than 20%
   • Less than 30%
   • Less than 45%

   Hint

   Remember the category of construction we're discussing.

4. 4.

   True or False: A higher Aggregate Crushing Value indicates a stronger aggregate.

   • True
   • False

   Hint

   Think about the implications of ACV on aggregate performance.

5. 5.

   Given an aggregate sample weight of 1000g and a total crushed weight of 700g, calculate the Aggregate Crushing Value (ACV) and determine if it is suitable for road use.

   Hint

   Focus on the formula for ACV.

6. 6.

   You have two aggregates: Aggregate A with an ACV of 25% and Aggregate B with an ACV of 50%. Discuss the implications for their use in a high-traffic road project.

   Hint

   Consider the required strength for heavy traffic.
