4. Technical Data
The primary ingredient of Slag Cement is granulated blast- furnace slag (GBFS) that is ground to a fine powder. When mixed with water and Portland cement (the traditional way that Slag Cement is used), the concrete sets and hardens into a solid monolithic mass. The hydration reaction forms a gel-like material called calcium silicate hydrate.
Supplementary Cementing Materials
Slag Cement, formerly referred to as ground, granulated blast-furnace slag, is a glassy, granular material formed when molten, iron blast-furnace slag is rapidly chilled - typically by water sprays or immersion in water - and subsequently ground to cement fineness. Slag cement is hydraulic and can be added to cement as an SCM.
