Sulfur speciation in untreated and alkali treated ground-granulated blast furnace slag [PDF]
Science of The Total Environment, 2017 Reduced sulfur species in ground-granulated blast furnace slag (GGBFS) play an important role in immobilizing radionuclide contaminants in caustic cement-GGBFS mixtures via reductive precipitation reaction. However, sulfur (S) speciation and its stability in GGBFS have not been clearly understood.

Durability Properties and Microstructure of Ground Granulated Blast Furnace Slag Cement Concrete [PDF]
International Journal of Concrete Structures and Materials, 2014 Ground granulated blast-furnace slag (GGBS) is a green construction material used to produce durable concrete. The secondary pozzolanic reactions can result in reduced pore connectivity; therefore, replacing partial amount of Portland cement (PC) with GGBS can significantly reduce the risk of sulfate attack, alkali–silica reactions and chloride ...
