- B0.0003Correct
- C0.001
- D0.003
Solution
Concept
Total shrinkage strain (IS 456 cl. 6.2.4.1)
Step-by-step solution
1. In the absence of test data the total shrinkage strain is taken as 0.0003.
Explanation
IS 456 permits 0.0003 as the approximate total shrinkage strain.
Why the other options are wrong
0.0001, 0.001 and 0.003 are not the code value.
Shortcut
Shrinkage 0.0003.
Correct answer: B) 0.0003
