Engineering Materials·MCQ explained

For which of the following is an ideal warehouse provided?

Try it first: pick an option, then read the explanation.

Correct answer: D. All of these

Detailed Explanation: Features of an Ideal Cement Warehouse

Why D (All of these) is correct: Cement is highly sensitive to moisture. Even 1% free moisture can initiate hydration, causing cement to set in the bag and become unusable. All three features protect against moisture ingress from different pathways: walls (lateral moisture), roof (rain), and windows (humid air).

Ideal Cement Warehouse Requirements

FeaturePurpose
Waterproof masonry wallsPrevents lateral moisture ingress through walls
Waterproof roofPrevents rain/dew from above; vital in monsoon conditions
Few, generally closed windowsReduces air circulation bringing humid air; minimises condensation
Raised wooden floor (pallets)Prevents ground moisture wicking up into bags
Limited pile height (max 10 bags)Prevents compaction and damage to lower bags
  • All three features are mandatory for an ideal cement warehouse — answer is All of these.
  • Cement stored beyond 3 months should be re-tested before use (IS 269 / IS 456).
  • FIFO (First In, First Out) must be strictly followed to prevent old stock sitting at the bottom.
