The act of keeping concrete wet to enable it to attain its full strength is known as:
Correct Answer: A. Curing
📚 Detailed Explanation: Curing Enables Concrete to Attain Full Strength
Why A (Curing) is correct: The technical term for the process of maintaining concrete in a wet condition to allow it to attain its full design strength through continued hydration is curing. The other options are general water-application terms with no specific technical meaning in concrete engineering.
Why Moisture Is Essential for Full Strength
| Scenario | Strength Outcome |
|---|---|
| No curing (air-drying from day 1) | ~50% of design strength; hydration stops as pores dry out |
| 3-day curing only | ~70% of design strength |
| 7-day curing (OPC minimum per IS 456) | ~85–90% of design strength |
| 28-day continuous curing | 100%+ of design strength |
Curing vs. Other Terms
| Term | Meaning | Used in Concrete Engineering? |
|---|---|---|
| Curing | Controlled moisture maintenance for strength development | Yes — standard technical term |
| Wetting | General application of water to a surface | No — not a concrete engineering term |
| Drenching | Thorough soaking with water | No |
| Quenching | Rapid cooling with water (used in metallurgy/firefighting) | No |
- Curing is the correct term for keeping concrete wet to attain full strength.
- Concrete left uncured may achieve only 50% of its design strength.
