Which of the following statements is incorrect? A. Higher Vee-Bee time shows lower workability B. Higher slump shows higher workability C. Higher compacting factor shows higher workability D. None of the above

The correct answer is: A. Higher Vee-Bee time shows lower workability.

Vee-Bee time is a test used to measure the consistency

of concrete. It is a measure of how long it takes for a concrete sample to flow through a standardized orifice. A higher Vee-Bee time indicates a more viscous concrete, which is less workable.

Slump is a test used to measure the workability of concrete. It is a measure of how much a concrete sample spreads out when it is placed in a mold and then released. A higher slump indicates a more workable concrete.

Compacting factor is a test

used to measure the workability of concrete. It is a measure of how much a concrete sample is compacted when it is placed in a mold and then subjected to a standard compaction effort. A higher compacting factor indicates a more workable concrete.

Therefore, the statement “Higher Vee-Bee time shows lower workability” is incorrect.
