The quick lime as it comes from kilns is called as-
-
A.
Hydraulic lime
-
B.
Lump lime
-
C.
Milk lime
-
D.
Hydrated lime
Correct Answer:
B. Lump lime
Explanation:
Lump lime is the correct answer because it refers to the direct, unprocessed output from a lime kiln. When limestone (calcium carbonate) undergoes calcination at high temperatures, it decomposes into calcium oxide, which remains in the form of hard, irregular chunks or lumps before any further crushing or hydration occurs.
Other forms represent different stages of processing or chemical compositions: - Hydraulic lime is produced from limestone containing clay and can set under water.
- Hydrated lime is a powder created by adding a specific amount of water to quicklime.
- Milk lime is a liquid suspension formed by adding an excess of water to hydrated lime.
