Slag cement is finely ground, granulated blast furnace slag (GGBFS), which is a by-product of the iron-manufacturing process. It has demonstrated compatibility with all types of portland cements, as well as with some combinations of fly ash or other SCMs. Slag cement can be used in concrete mixes either as a separate component or as a ...

The hydration products of slag cement are generally found to be more gel-like (less crystalline) than the products of hydration of portland cement; thus, they reduce the permeability of the cement paste (ACI 233R). Slags are used as a replacement of portland cement in amounts typically between 25 and 70% of the total mass of cementitious …

Slag cement is a hydraulic binder that, like portland cement, reacts with water to form cementitious material (calcium-silicate hydrate or CSH). It also, similar to a pozzolan, consumes by-product calcium hydroxide from the hydration of portland cement to form additional CSH. The resulting cement paste is stronger and denser, thus improving the ...

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.
