What is slag cement

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing Limestoney granules that yield desired reactive cementitious characteristics when ground into

Manufacturing - Skyway Cement

Skyway Cement receives granulated slag from a US steel manufacturer in Gary, Indiana. In the blast furnace at the steel works, slag is produced when the mineral components of the metal refining process separate from and float on the molten iron. The iron is drawn off to be further refined into steel and the slag is drawn off to be granulated.

Slag Cement - an overview ScienceDirect Topics

The hydration process of slag cement is more complicated than Portland cement. At first, the minerals in cement clinker react with water and generate calcium silicate hydrate, calcium aluminate hydrate, calcium ferrite hydrate and calcium hydroxide. Calcium hydroxide and gypsum mixed in cement are the alkali activator and the sulfate activator for slag respectively which react with active silicon oxide and aluminum oxide again to generate calcium carbonate hydrate, calcium aluminate hydrate,
