What is Slag Cement? (with pictures)

Slag cement has actually been used in concrete projects in the United States for over a century. Its earliest use was documented in 1774, when it was combined with slaked lime and used as a mortar.This cement was first used commercially in Germany in the 1860s, and it was such a success that engineers in 1889 decided to build the Paris underground metro using slag-lime cement.
