The batch plant operator measures the aggregate moisture and finds that the fine aggregate moisture is at 5%. The coarse aggregate, just delivered, has a moisture content of 0.5%. The operator computes the add-water as follows: Fine aggregate = 1100 lbs x (0.05 – 0.02) = + 33 lbs Coarse aggregate = 2000 lbs x (0.005 – 0.01) = - 10 lbs

Determining Moisture in Aggregate for Mix Proportioning ...

Mar 01, 1986  The difference in weight represents the total moisture content of the aggregate. For making batch calculations it is handiest if moisture has been calculated as percent of the SSD weight of the aggregate. The total moisture measured in the test represents both the free moisture and the moisture that the aggregate absorbs.
