Question 1.
What is a Gradation Curve?
Show hintHide hint
Think of how we can visually show size distribution.
Question 2.
Define Fuller's Formula.
Show hintHide hint
Remember it involves the maximum size and a specific aggregate size.
3Question 3.
What does the Trial and Error Method involve?
- Calculating percentages
- Plotting gradation curves
- Using random aggregates
Show hintHide hint
Think about the exploratory nature of the method.
4Question 4.
True or False: Fuller's Formula applies only to the Trial and Error Method.
- True
- False
Show hintHide hint
Consider how each method functions.
Question 5.
Given different aggregate sizes, use the trial and error method to propose a potential combination that maximizes strength while maintaining workability.
Show hintHide hint
Consider performance requirements.
Question 6.
Using Fuller's Formula, if the maximum aggregate size is increased to 40mm, how does that impact the percentages calculated for smaller sizes? Provide computations.
Show hintHide hint
Look at how the maximum size affects the outcome.
