Portland Slag Cement, Cement Grade: General

Slag is a high glass, non-metallic Product Containing Silicate and Alumino-Silicates of lime. The slag produced contain more than 90% glass content. BF slag is the product from the controlled process of iron production which results from a uniform composition. Whereas in the case of Portland pozzolana cement Quality of fly ash from ESP widely

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
