Vee–Bee consistometer test is suitable for findingworkability ofa)rich concreteb)lean concretec)stiff concreted)all the aboveCorrect answer is option 'B'. Can you explain this answer?

Answer

Explanation:

The Vee-Bee Consistometer Test is a popular test that determines the workability of concrete, which is the ease of which concrete can be mixed, transported, placed, and compacted into a specific shape without any segregation. The test is done by measuring the time taken by the concrete to flow down through a standard height under the vibration of a standard process. The higher the time taken, the less workable the concrete is, and vice versa.

Applicability to different types of concrete:

Rich concrete: Rich concrete contains a higher proportion of cement, fine aggregates, and water, and hence has better workability than lean concrete. The Vee-Bee Consistometer Test is suitable for both rich and lean concrete.

Lean concrete: Lean concrete contains a lower proportion of cement, fine aggregates, and water, and hence has poorer workability than rich concrete. The Vee-Bee Consistometer Test is particularly useful for lean concrete as it helps in determining the minimum water content required to achieve adequate workability.

Stiff concrete: Stiff concrete has very low workability and is difficult to mix, transport, and place. The Vee-Bee Consistometer Test is not suitable for stiff concrete as the concrete may not flow through the apparatus, and hence, the results may not be accurate.

Therefore, the correct answer is option B - the Vee-Bee Consistometer Test is suitable for determining the workability of lean concrete.

Answer
