Question:
Which type of cement is best suited for underwater construction?
Which type of cement is best suited for underwater construction?
Show Hint
Quick setting cement is preferred for underwater construction because it sets rapidly and reduces the chance of washout.
Updated On: May 7, 2026
- Ordinary Portland cement
- Quick setting cement
- Sulphate resistance cement
- Pozzolanic cement
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Underwater construction requires cement that can set quickly.
When construction is done under water, the cement paste may be disturbed or washed away if it remains plastic for a long time.
Therefore, quick setting is very useful in such conditions.
Quick setting cement sets faster than ordinary Portland cement.
It is useful for repair work, underwater construction, and situations where early setting is required.
Ordinary Portland cement has normal setting time and is not specially designed for underwater work.
Sulphate resisting cement is used where sulphate attack is expected.
Pozzolanic cement is useful for durability and reduced heat of hydration, but it is not the best option for quick underwater setting.
Therefore, the cement best suited for underwater construction is:
\[
\text{Quick setting cement}.
\]
