Q: Bulking of sand is caused by
A) Cement
B) Air pressure
C) Moisture
D) Fineness
βœ… Correct Answer: C
Explanation: Moisture in fine sand causes it to occupy more volume than dry sand.
Q: RCC combines concrete and steel because
A) Both are cheap
B) One resists fire
C) One resists tension, the other compression
D) Both are light
