How do I determine the moisture content of an …
I dont see anyway to determine the moisture content without removing it from the bag and drying. Unless you are looking at a different process that does not include water, the only real thing I would be concerned with is the water absorption of the aggregate. This controls the water-cement ratio of your design which affects strength.

Determination of Moisture Content of Aggregates …
Determination of moisture content in total is of key significance in the control of the nature of cement especially as for workability and quality. The measurement of the moisture content of aggregates is basically a very simple process. But it is complicated by several factors.
Determining Moisture in Aggregate for Mix …
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.
Moisture Content - engr.psu.edu
The AD and wet states represent the variable moisture contents that will exist in stockpiled aggregates. The SSD state is the best choice as a reference state for the following reasons: It represents the "equilibrium moisture" state of the aggregate in concrete; that is, the aggregate will neither absorb water nor give up water to the paste.

prossice of find moister content of aggregate. ... The moisture content of an aggregate is an important factor when developing the proper water/cementitious material ratio. All aggregates contain some moisture based on the porosity of the particles and the moisture condition of the storage area.
Determination of Moisture Content in Soil | Protocol
Soils normally contain a finite amount of water, which can be expressed as the “soil moisture content.” This moisture exists within the pore spaces in between soil aggregates (inter-aggregate pore space) and within soil aggregates (intra-aggregate pore space) (Figure 1). Normally this pore space is occupied by air and/or water.
