Slag Cement Lehigh Hanson Inc.

Slag cement is as old as iron-making itself. In the 1700s, it was combined with lime to make mortar. One of the first major uses of slag-lime cements was construction of the Paris underground in the late 1800s. In the U.S., blends of slag and portland cements were introduced in 1896. Today, slag cement can account for 30% to 50% of the cement ...

Why use Fly Ash and Slag in Concrete Bay Lynx

Why use Fly Ash and Slag in Concrete Bay Lynx

Slag happens when iron ore is melted. The molten iron sinks to the bottom, while the slag will float on the top of the iron. See the diagram below: Another difference between slag and fly ash is that while fly ash will rarely surpass 35% of the cement content, slag can substitute 50% of the cement content, or even higher for different applications.
