Determining Moisture in Aggregate for Mix Proportioning
The total moisture measured in the test represents both the free moisture and the moisture that the aggregate absorbs Only the free moisture becomes part of the mix water The absorbed water, usually about 1 percent, remains within the aggregate If the coarse aggregate is unusually porous, the absorption should be determined by a separate testAggregate stored in a stockpile or bin is typically in a wet condition, meaning it contains absorbed water and moisture coating the surface, called free or surface moisture The total moisture content of an aggregate sample is the sum of the absorbed moisture and the free surface moisture Aggregate Moisture and Making Adjustments to Concrete
