AAbout 5 percent at 5 percent moisture
BAbout 40 percent at 10 percent moisture
CAbout 25 percent at 4 percent moisture
DAbout 75 percent at 15 percent moisture
Answer & Solution
Correct answer: B. About 40 percent at 10 percent moisture
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.
