Question 1.
What is the effect of increasing the water-cement ratio on workability?
Show hintHide hint
Think about fluidity.
Question 2.
What type of aggregate shape promotes better workability?
Show hintHide hint
Remember about how aggregates roll.
3Question 3.
What happens to workability if the water-cement ratio is increased?
- Decreases
- Remains the same
- Increases
Show hintHide hint
Focus on fluidity.
4Question 4.
True or False: Angular aggregates improve workability more than rounded aggregates.
- True
- False
Show hintHide hint
Think about how the shape affects movement.
Question 5.
During a hot summer day, concrete mix is prepared with a high water-cement ratio. Analyze the potential effects this may have on both workability and final strength.
Show hintHide hint
Consider the implications of water in the mix.
Question 6.
In a project using angular aggregates, engineers report poor workability in concrete placement. Suggest strategies to improve the situation.
Show hintHide hint
Focus on altering the physical properties of the aggregates.
