Question 1.
What does the Aggregate Crushing Value (ACV) measure?
Show hintHide hint
Think about what happens to aggregates under pressure.
Question 2.
Why is a lower ACV preferred in construction?
Show hintHide hint
Consider what high values might mean for structural longevity.
3Question 3.
What does the Aggregate Crushing Value (ACV) measure?
- The weight of aggregate
- The resistance to crushing
- The maximum size of aggregates
Show hintHide hint
Think about the test's focus on structural integrity.
4Question 4.
A lower ACV value is preferred for which application?
- High-rise buildings
- Pavements for roads
- Non-structural landscaping
Show hintHide hint
Consider the durability needs for different constructions.
Question 5.
An aggregate sample has a weight of 1000 grams. After the ACV test, the weight of crushed material is 250 grams. Calculate the ACV percentage.
Show hintHide hint
Remember the formula to calculate percentage.
Question 6.
The ACV test shows two different aggregates with values 20% and 40%. Discuss which aggregate would be more suitable for a high-traffic road.
Show hintHide hint
Reflect on the importance of strength in high-traffic applications.
