233R-17: Guide to the Use of Slag Cement in Concrete and ...

The use of slag cement as a cementitious material dates back to 1774, when a mortar was made using slag cement in combination with slaked lime (Mather 1957). In 1862, a granulation process was proposed to facilitate removal and handling of iron blast-furnace slag leaving the blast furnace. The use of granulation produced glassy material that played

Why use Fly Ash and Slag in Concrete? - Bay-Lynx ...

With cement being the costliest ingredient, substituting fly ash or slag can help maintain a stronger mix at a lower cost. Fly ash and Slag will typically be 18% cheaper than Portland cement. When a mix includes 20% fly ash, this will provide savings of 3.5% in cost. The advantage of slag is its ability to substitute more of cement.

slag cement proportioning

Why use Slag Cement in Concrete? In concrete, slag cement may be proportioned from 20 to 80 percent depending on the application. It is substituted for portland cement on a one-to-one basis by mass. The proportion of slag cement used is usually dictated by requirements for strength, durability, time of set, heat generation, or the resistance of ...
