Shrinkage of concrete depends on i. Humidity of atmosphere ii. Passage of time iii. Stress
- AOnly (i)
- B(i) and (ii)Correct
- COnly (iii)
- D(i), (ii) and (iii)
Solution
Concept
Shrinkage vs creep
Step-by-step solution
1. Shrinkage is a moisture-loss effect that depends on ambient humidity and time. 2. It is independent of applied stress (creep depends on stress).
Explanation
Shrinkage occurs without load.
Why the other options are wrong
Stress affects creep, not shrinkage.
Shortcut
Shrinkage: humidity + time, no stress.
Common mistake
Confusing shrinkage with creep.
Correct answer: B) (i) and (ii)
