The weight of a sample of coarse aggregate was measured under various conditions with the following results:
oven-dry weight in air 1076.3 g
air-dry weight in air 1083.3 g
saturated-surface-dry weight in air 1089.2 g
weight of saturated sample in water 681.5 g
calculate
a) air-dry moisture content
b) absorption capacity
c) effective absorption
d) bulk specific gravity
e) saturated surface-dry bulk specific gravity
