Question 2.
Provide an example of a coarse aggregate.
Show hintHide hint
Consider materials that are visibly larger in size.
3Question 3.
Fine aggregates are retained on which size sieve?
- 4.75 mm
- 75-micron
- 10 mm
Show hintHide hint
Remember the size that differentiates fine from coarse.
4Question 4.
True or False: Coarse aggregates are smaller than fine aggregates.
- True
- False
Show hintHide hint
Think about their definitions.
Question 5.
A concrete mix design requires specific sizes of aggregates. If a batch contains 40% fine aggregates instead of the required 30%, how might this impact the concrete's final properties?
Show hintHide hint
Consider how the excess affects cohesion and overall strength.
Question 6.
In a construction project, the engineer found that the coarse aggregates didn't meet specifications. What tests might they conduct to assess the suitability of these aggregates?
Show hintHide hint
Think about how you would verify if materials meet building standards.
