4.6 A week later, after long, hot, dry days, another sample is taken
from the same material noted in question 5. The wet weight is 800 g, but
the dry weight is 795 g. How much free moisture will be available
from the sand when batched today?

None
11 lb (5 kg) per 1000 lb (450 kg) of sand

The quantities for aggregates are given in their dry condition. To change them to
saturated surface dry (SSD), you need to add absorption.
Dry
Sand 1250 lb (568 kg) x 1.013
Stone 1700 lb (772 kg) x 1.0085
SSD
1266.25 (574.88 kg) use 1266 lb (575 kg)
1714.45 (778.36 kg) use 1714 lb (778 kg)
C. None
The new sample has a wet weight of 800 g and a dry weight of 795 g. The
total moisture is (800 - 795)/795 * 100 = 0.6%
This means that the absorption of the sand has not been met.
A. 6 months for scales, 3 months for meters

panel with a note calling for an insert at a given location but on the far side
would
indicate a location on the bottom of the piece.
