Question 1.
What does specific gravity measure?
Show hintHide hint
Think about how it compares to water.
Question 2.
What is water absorption expressed as?
Show hintHide hint
Remember how we measure the weight before absorbing water.
3Question 3.
What does specific gravity tell us about aggregates?
- It indicates porosity
- It indicates compressive strength
- It indicates density
Show hintHide hint
Consider how weight relates to volume.
4Question 4.

- True
- False
Show hintHide hint
Think about the role of aggregates in concrete.
Question 5.
If an aggregate sample weighs 80 kg in air and 60 kg when submerged in water, calculate its specific gravity.
Show hintHide hint
Use the formula for specific gravity involving the buoyant force.
Question 6.
Discuss the implications of using aggregates with a water absorption of 5% in a concrete mix intended for high durability structures.
Show hintHide hint
Consider the importance of maintaining a correct water-cement ratio.
