Extremely fine sand, per the source, may show a maximum bulking of approximately:
A{'text': 'About 5 percent at 5 percent moisture', 'label': 'A'}
B{'text': 'About 40 percent at 10 percent moisture', 'label': 'B'}
C{'text': 'About 25 percent at 4 percent moisture', 'label': 'C'}
D{'text': 'About 75 percent at 15 percent moisture', 'label': 'D'}
Answer & Solution
Correct answer: B. {'text': 'About 40 percent at 10 percent moisture', 'label': 'B'}
1. §2.2.9 states: 'Fine sand bulks more than coarse sand. The bulking of extremely fine sand could be as much as 40 percent at a moisture content of about 10 percent.'
2. Bulking is also the reason a volume-batching mix needs sand-volume correction.
