Cement Plants: Clays and Shales
Boulder Clays were produced as superficial deposits during the ice ages, and so are 0-2 million years old. Because they were formed by ice, they do not occur in the south of England and southern Ireland. The mechanism of formation involves a grinding action on rocks which gives rise to material of floury fineness in addition to larger fragments.

Shepherdstown Cement Mill
Because natural, or hydraulic, cement is waterproof and hardens underwater, it was used in large quantities in building the canal. Cement mills sprang up along the Potomac, and Shepherdstown's was among the largest. Built into a nearby hillside, the first kiln was in operation by April 1829. The temperature of the large kiln was difficult to
