• Chalk is porous and often has high moisture content that leads it to its use in the 'semidry/wet' manufacturing process of making cement. This particular process represents some 16% of total production. Shale • Shale is a pure sedimentary rock made of very fine silt, clay and quarz. Shale falls in the category of mudstones.

The cement industry has boosted efficiency by concentrating new capital investment in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energyintensive wet process. Since 1974, the number of wet process kilns has dropped from 234 to 25 a decline of 89 percent while the number of dry process kilns has only been reduced from 198 to 124.
