Water content
Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood.Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials'' porosity at saturation. It can be given on a volumetric or mass

crushed rock and mineral samples and processing methods
Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface water and groundwater pollution, erosion, and sedimentation (see Chapter 14). The mining process involves the excavation of large amounts of waste rock in order to remove the desired mineral ore (Fig. 12.6). The ore is then crushed into

Typical oven- dry density values range from 2240 to 2430 Mg/ m 3 for the coarse fraction and 2130 to 2410 Mg/m 3 for the fi ne fraction. The water absorption values range between 4 to 7% for the coarse fraction and 6 to 9% for the fi ne fraction.

Aggregates for Concrete
Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.
