- Sieve
- Lechatelier apparatus
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Vicat apparatus is used to determine the consistency and setting time of cement paste.
Step 1: Initial setting time is the time at which cement paste starts losing plasticity.
Step 2: Vicat apparatus uses a standard needle to measure penetration in cement paste.
Step 3: When the needle penetration reaches the specified value, the initial setting time is recorded.
Step 4: Lechatelier apparatus is used for soundness test, and sieve is used for fineness test. Therefore, initial setting time of cement is measured by: \[ \boxed{\text{Vicat apparatus}} \]
