4Question 4.
True or False: The Vee-Bee test is effective for high slump concrete.
- True
- False
Show hintHide hint
Think about the type of concrete the test is designed for.
Question 5.
A construction site is using a concrete mix that frequently shows shear slump during testing. What are possible adjustments that can be made to improve the mix's cohesiveness?
Show hintHide hint
Consider what changes affect cohesiveness and cohesion.
Question 6.
During a compacting factor test, the weight of the partially compacted concrete was found to be significantly lower than expected. What does this imply about the concrete's workability, and what steps should be taken?
Show hintHide hint
Think about the relationship of weight in compacted versus loose concrete.
