For the surface moisture content of fine aggregate, vary the testing frequency depending on the uniformity of supply. A change of 1 percent in the moisture content of sand, if not compensated for during batching, may change the penetration of concrete as much as 3/4 inch and the compressive strength as much as 300 psi.

DETERMINATION OF MOISTURE AND TOTAL SOLIDS

The mass of water is related to the number of water molecules (n W) by the following expression: m w = n w M w /N A, where M w is the molecular weight of water (18.0 g per mole) and N A is Avadagro's number (6.02 ´ 10 23 molecules per mole). In principle, the moisture content of a food can therefore be determined accurately by measuring the ...

Engineering Field Manual

Water content (w) is the percentage of the weight of water to the weight of the dry solids. The term "moisture content" is sometimes used instead of "water content." A saturated soil has its voids completely filled with water, and its water content is denoted by w,,. Soil below the water table is usually considered to be saturated.
