Ground granulated blast furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. The main novelty of this study is to find the durability properties such as …

Ground granulated blast furnace slag also has a lower heat of hydration and, hence, generates less heat during concrete production and curing. GGBFS is a desirable material to utilize in mass concrete placements where control of temperatures is an issue. GGBFS can be used instead of cement with the ratios from 10 to 90%.

Ground granulated blast furnace slag (GGBS) is a by-product of pig-iron production. The production of 1 t GGBS emits approximately 0.14 t CO 2 (Özbay et al., 2016), accounting for only about 16% of the CO 2 emission from cement production (Wu et al., 2020). Thus, extensive utilization of high volume GGBS to replace cement is an …
