Question 2.
What role does aggregate volume play in concrete shrinkage?
Show hintHide hint
Imagine aggregates as tiny bricks holding the mix together.
3Question 3.
What does a higher water-cement ratio do to concrete shrinkage?
- Reduces shrinkage
- Increases shrinkage
- Has no effect
Show hintHide hint
Think about moisture in the mix and how it escapes.
4Question 4.
