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 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 slaglime cement.
Greening of Slag Cement Concrete| Concrete Construction ...
Aug 31, 2011 · In most concrete made with slag cement, the surface becomes light gray or white within hours after the concrete surface has been exposed to direct sunlight and air. In fact, slag cement often is used because it enhances the whiteness and brightness of concrete. The interior of the concrete, however, can remain bluegreen indefinitely.
