DETERMINATION OF MOISTURE AND TOTAL SOLIDS - UMass

Drying foods in a vacuum oven therefore has a number of advantages over conventional oven drying techniques. If the sample is heated at the same temperature, drying can be carried out much quicker. Alternatively, lower temperatures can be used to remove the moisture ( e.g. 70 o C instead of 100 o C), and so problems associated with degradation ...

Moisture Content - Pavement Interactive

In general, there are four aggregate moisture conditions: Oven-dry (OD). All moisture is removed by heating the aggregate in an oven at 105 C (221 F) to constant weight (this usually constitutes heating it overnight). All pores connected to the surface are empty and the aggregate is fully absorbent. Airdry (AD).

Determining Moisture in Aggregate for Mix Proportioning

Determining Moisture in Aggregate for Mix Proportioning

Mar 01, 1986 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 test.

May 31, 2013 The absorption of the aggregate indicates the quantity of water which will be absorbed into the pore structure. Most commonly, aggregates will have a moisture content that is either below or above this absorption limit. When batching, it is of critical importance to account for this water. Obviously, if the aggregates are in a surface wet ...
