Our highest performing cement.
Slag cement is produced by finely grinding granulated blast furnace slag, a glassy by-product of iron production, and blending it with Portland cement to create a product that has a number of advantages over mixes containing 100% Portland cement.
In addition to it’s high strength and durability, slag cement is an environmentally “green” product. In providing a beneficial use of an industrial by-product, it reduces the energy required to produce concrete while at the same time improving the quality of the concrete for a more durable, longer lasting product. Slag cement can also be used to help achieve LEED points.
