Question 1.
What is the acceptable range for specific gravity in aggregates?
Show hintHide hint
It's a range pertaining to density comparisons.
Question 2.
What should water absorption preferably be less than?
Show hintHide hint
Think of it as a percentage less than two.
3Question 3.
What is the typical range of specific gravity for aggregates?
- 2.0-2.5
- 2.6-2.9
- 3.0-3.5
Show hintHide hint
Remember it is slightly above 2.
4Question 4.
Is water absorption greater than 2% acceptable for aggregate efficacy?
- True
- False
Show hintHide hint
Think of how water content impacts mix integrity.
Question 5.
You are tasked with evaluating two aggregates for a construction project. Aggregate A has a specific gravity of 2.5 and water absorption of 3%, while Aggregate B has a specific gravity of 2.8 and water absorption of 1.8%. Which aggregate would you recommend and why?
Show hintHide hint
Evaluate the implications of each aggregate’s properties.
Question 6.
Design a scenario where you might encounter issues due to high levels of water absorption in the aggregates used during a rainy season on-site. Discuss the potential consequences.
Show hintHide hint
Consider how aggregates interact with water during various weather conditions.
