The prime materials required for the yield of SCGC are the binder (GGBFS), alkali-activated solution (AAS) which is prepared by the combination of sodium silicate (SS) solution and particular molar (12 M here) sodium hydroxide (SH) solution in ratio 2.5, aggregates (natural coarse and fine aggregates), superplasticizer (SP) and extra water …
The significant challenges in the construction industry, such as resource depletion and carbon dioxide emission, has opened the way for concrete development with immense strength and better durability. Numerous studies were carried out by replacing the basic materials, and various admixtures were introduced into concrete. One such …
Supplementary cementitious materials (SCMs) have been widely used to replace cement in recent years in order to reduce the burden of cement on the environment. In this study, fly ash (FA) and ground-granulated blast furnace slag (GGBFS) were used as long-term 40%, 50% and 60% replacement cement in order to explore the mechanical …
Ground granulated blast furnace slag (GGBFS) is a granular glass composed primarily of calcium oxide (CaO), silicon dioxide (SiO 2), aluminium oxide (Al 2 O 3), and magnesium oxide (MgO) [76,77,78,79]. It is an amorphous by-product of the production of pig iron from iron ore, coke combustion residue, and fluxes such as …

Among the constituent materials in concrete, cement is the largest contributor to the release and emission of carbon dioxide (CO 2).As much as 4%–6% of the global CO 2 emissions is due to the production of cement. This is due to direct emission from calcination of calcium carbonate as well as indirect emission from combustion of fossil fuel used for …
The physical properties of Ground Granulated blast furnace slag (GGBFS) provides advantages to the concrete in fresh state as well as in its hardened state. It is always recommended for a concrete mix design, that would provide us with a denser mass of concrete, i.e. a solid that is free from voids. GGBS play an important role in making the ...

GGBFS contains silico-aluminous components that exist in high-activity amorphous phases [35], [36], [37]. Thus, GGBFS is also a common raw material of geopolymer. However, geopolymers prepared by GGBFS set too fast, had high shrinkage, and were easy to crack [38]. And FA could be used to adjust the setting time of GGBFS …
