Using Slag Cement in Sustainable Construction
Slag cement is a byproduct of iron production in a blast furnace. It is a hydraulic cement that can replace between 20 to 80 percent of the portland cement in concrete (depending on application, see Table 1) and helps makes concrete even greener. Slag cement contributes the following sustainability ben-efits to concrete:

Benefits of using slag cement
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 material.
