Lime MCQ with answer and solution

Concept

Workability of lime putty/mortar is measured on a flow table using a truncated conical mould.

Step-by-step solution

1. Recall the standard tests on building lime (IS 6932). 2. Workability is checked with a standard flow table and a truncated conical mould. 3. The autoclave is used for soundness, and Vicat's apparatus for setting time. 4. The slump cone is used for concrete, not lime. 5. So the answer is (A).

Explanation

Lime is filled in a truncated cone mould on a flow table. The mould is lifted and the table is jolted. The spread of the lime shows its workability.

Why the other options are wrong

B: Autoclave is for soundness (expansion). C: Vicat's apparatus is for setting time and consistency. D: Slump cone is for concrete workability.

Shortcut

Lime workability = flow table; concrete workability = slump cone.

Common mistake

Choosing the slump cone because it is the most familiar workability test.
