Note: If the maximum number of cycles (20) is reached
and the aggregate is still not dry, the unit will display a
message prompting the user to turn the sample and
restart the drying operations. At this point remove the
fixture from the chamber, shake the fixture to re-orient
the aggregates and replace inside the sample
chamber. Close the lid and press Enter. The unit will
continue until the sample is completely dry.
12. Determine the moisture content by the following
equation
Moisture Content= Weight A Weight B
Aggregate Type
Sample Weight
Crushed fine aggregates
and sand
100-150 grams
Rounded fine aggregates
300-400 grams
Coarse aggregates
400-500 grams
Note: The above estimates on sample weights are based
on saturated aggregate samples.
If the aggregate is not saturated, higher sample
weights can be used.
