“…The test for sorptivity was conducted on 100 mm cubes [18]. Cubes were placed in a hot air oven at a temperature of 105 °C up to which constant mass is obtained at an interval of time [19] and the weight was noted [20]. Then, the specimen is immersed in water for different interval of time (30 and 60 till the constant mass was obtained and it was noted.…”

Utilization of various mineral admixtures in producing mortar decreases the porosity and capillarity, hence improves the durability in opposition to water and competitive solutions. In this research work, Ground Granulated Blast Furnace Slag is used to replace 30 percent, 60 percent, and 70% of ordinary Portland cement (OPC) (GGBFS). Mechanical property (compressive strength) and durability properties (permeability, porosity, and sorptivity) of high-performance concrete (HPC) are tested. Water permeability of M85 is measured using three cell permeability apparatus. Compressive strength, porosity, and sorptivity of the same mixes are also found. According to the test results of HPC, 30% replacement level of GGBFS gives higher compressive strength than 60% and 70% replacement levels of GGBFS. An equation is developed for permeability of HPC based on mechanical strength and porosity. It is found that coefficient of permeability of water for HPC mixes ranges from 5.1 × 10-11 cm/sec to 7.8 × 10-11 cm/sec. It is concluded that 30% GGBFS used in HPC produces less porosity, less permeability, and less sorptivity than compared to other replacement levels.

“…Geopolymer represents an innovative binding material generated through the polymerization of diverse industrial by-products, including GGBS, fly ash (FA), red mud (RM), metakaolin (MK), pond ash (PA), silica fume (SF), among others, all of which contain ample silicon dioxide (SiO 2 ) and aluminium oxide (Al 2 O 3 ) ions through alkali activation [9,10]. This process necessitates the utilization of an alkali activator solution (AAS) to stimulate the SiO 2 and Al 2 O 3 components present in the aluminosilicate precursors, resulting in the formation of calcium aluminate silicate hydrate and sodium aluminate silicate hydrate gels.…”

Geopolymer binder offers a more sustainable choice for producing concrete in comparison to traditional ordinary Portland cement (OPC). The substitution of geopolymer binder for construction practices can decrease carbon dioxide emissions by decreasing OPC usage and repurposing industrial waste materials like ground granulated blast furnace slag (GGBS), fly ash, red mud, silica fume. In order to assess the suitability of GGBS as a binding material, it is essential to conduct conventional tests like consistency, setting times, and compressive strength, which are widely employed in cement testing. This study produced alkali activated paste (AAP) from GGBS and an alkaline activator comprising sodium hydroxide at various molarities from 1M to 8M. This investigation focused on the compressive strength of alkali-activated GGBS-based AAP under varying alkali activation molarities and curing conditions, including ambient, hot air oven, and humidity chamber curing. Additionally, the end reaction products of AAP showing higher compressive strength were examined for scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis. The experimental outcomes indicated that GGBS reduced the final setting time of AAP while increasing its compressive strength. Additionally, increasing the quantity of NaOH in the AAP increased its compressive strength. Furthermore, the research findings indicated that the mechanical properties of the alkali-activated GGBS-based material were notably influenced by the chosen curing conditions. Specifically, ambient curing demonstrated superior compressive strength, measuring at 47.06 MPa after 28 days, surpassing the results obtained from hot air oven curing and humidity curing.
