What is Blast Furnace Slag Cement? Blast furnace slag cement is a blend of ordinary Portland cement and finely granulated blast furnace slag, a byproduct from steel manufacturing, typically constituting less than 70% of the cement composition. Ground granulated blast furnace slag cement (GGBFS) is characterized by fine glassy …

Cement kiln dust can be used in cement bricks, concrete, or mortar as cementitious materials, and steel slag can serve various purposes, depending on its pozzolanic and hydration activity and f-CaO/MgO ratio, such as a supplementary cementitious material (SCM), pure binder material with the addition of carbonation …

Slag cement use can be traced to the 1700s when the material was combined with lime to make mortars. The first United States production was in 1896. Until the 1950s, granulated slag was used in the manufacture …

1. Introduction. Research on low-emission concrete, also called green concrete, is focused on waste recycling [1,2] and the reduction of Portland clinker in the concrete composition without affecting mechanical properties.Concrete additives, such as fly ash and blast furnace slag, are used for this purpose [3,4,5].Fly ash (FA) is a by …
