Workability of Concrete can be measured by
- ASlump test
- BCompaction factor test
- CVee-Bee consistency test
- DAll of the aboveCorrect
Solution
Concept
Measurement methods of concrete workability
Formula
NONE
Step-by-step solution
1. Workability of concrete is the ease with which it can be mixed, placed, compacted, and finished. 2. Slump test, Compaction factor test, and Vee-Bee consistency test are standard methods used to determine workability based on different consistency ranges. 3. Therefore, all the listed methods are used to measure the workability of concrete. Answer: D
Explanation
Workability of concrete refers to the ease with which it can be mixed, placed, compacted, and finished smoothly. The slump test, compaction factor test, and Vee-Bee consistency test are all standard methods used to evaluate various aspects of concrete workability. Therefore, all of the listed testing methods are correct.
Why the other options are wrong
A) Slump test is only one of several tests used to measure workability. B) Compaction factor test measures workability alongside other standardized tests. C) Vee-Bee consistency test measures workability, making all listed options valid.
Shortcut
Concrete workability is evaluated using Slump, Compaction Factor, Vee-Bee, and Flow Table tests.
Common mistake
Selecting the slump test only because it is most familiar, ignoring that all options measure concrete workability.
Correct answer: D) All of the above
