“…Mathematical models were planned to predict concrete strengths when exposed to fireplace flame thanks to various tests like compressive, tensile, and flexural strengths. 100 x 100 x 100mm cubes, 100mm diameter 200mm long cylinders, and 100 x 100 x 500mm beams were forged as specimens to test compressive, flexural, and split tensile strengths, respectively, according to IS [11]. Beams, cubes and cylinders specimen are shown in Fig.…”

The fire resistance of concrete with low fire resistance and meagre fire resistance can be improved by replacing the cement in the concrete mixture with different GGBS ratios. By partially substituting cement with GGBS (ground blast furnace slag), which can be used as an additive to assure excellent heat resistance in concrete, the GGBS can help lower the price of concrete mixtures, prevent concrete from cracking, reduce high temperatures and increase compressive strength. For OPC concrete mixtures, the exact optimal cement substitution rate of GGBS (15-60%, in steps of 15%) must be reached for mechanical (compressive strength, tensile strength and flexural strength) analysis, durability (constant pressure and water absorption), GGBS concrete mixture mass loss due to acid attack and microstructure characteristics (FESEM and FTIR), assuming a water-cement ratio of 0.4. (Mixture 1 with 100% and Mixture 2 with the best GGBS percentage) After exposure to the flame, the resistance is calculated. Curing HSC performance is observed under the influence of thermal annealing. Higher temperature is observed in various mixtures and densities.

“…Finally, these results were compared with the compressive strength of 28 days of water-cured concrete specimens. Te sulfuric acid attack tests were also performed in a similar method with the only diference that the pH value was equal to 1.0 [62][63][64][65][66][67][68][69][70][71][72].…”

“…Te improvement of magnesium sulfate resistance in the binary specimen of WGP15 may be due to the sacrifcial behavior of WGP. WGP produces compounds that are not as harmful as those formed by the decomposition of cement hydration products exposed to the magnesium sulfate environment [62,98]. WGP leaches alkali ions of Na + and Si + into the solution, which leads to the neutralization of magnesium sulfate.…”

“…Te lower weight gain of the binary specimen of WGP15 compared to the Ctrl specimen is related to the reduction of C 3 A due to the decrease in the extent of cement and the consumption of Ca(OH) 2 due to the pozzolanic reaction, which ultimately reduces the formation of gypsum and ettringite. In addition, the reaction of magnesium sulfate with WGP produces compounds with a lower density than the reactants, which might be why the binary specimen of WGP15 does not show the same weight gain shown by the other specimens [62]. Mostofnejad et al [63] evaluated the durability of concrete containing recycled concrete aggregates with WGP in the magnesium sulfate environment.…”

By considering the adverse environmental impacts of the cement manufacturing process, there have been many efforts for cement replacement by supplementary cementitious materials (SCMs), which can enhance the produced concrete performance while reducing cement consumption. This study evaluated the effects of various proportions of silica fume (SF), waste glass powder (WGP), and ground granulated blast furnace slag (GGBFS) on the mechanical and durability properties of concrete. The properties evaluated in this study include compressive, tensile, and flexural strength, magnesium sulfate and sulfuric acid attack, surface resistivity, rapid chloride penetrability test (RCPT), water absorption, depth of penetration of water, and microstructure analysis by scanning electron microscopy (SEM). The results of compressive, tensile, and flexural strength, chloride ion penetrability, and water absorption tests showed that adding 5% of SF to mixtures containing 10% WGP or 10% GGBFS improved concrete performance significantly due to packing density and synergistic effect; however, adding 5% of SF to concrete mixtures decreased the resistance against the magnesium sulfate and sulfuric acid attack. The binary mixture of 15% of WGP showed appropriate performance against the magnesium sulfate and sulfuric acid attack, which may be due to the sacrificial nature of WGP. In addition, the binary mixtures of 15% of WGP and 15% of GGBFS reduced the depth of penetration of water by 45%. Microstructure analysis by SEM showed that the presence of SF, along with WGP and GGBFS, improves the packing density. Finally, adding 5% of SF is suggested to improve the properties of concrete mixtures containing WGP and GGBFS.

Curing Effect on Durability of Cement Mortar with GGBS: Experimental and Numerical Study

In this paper, supplementary cementitious materials are used as a substitute for cement to decrease carbon dioxide emissions. A by-product of the iron manufacturing industry, ground granulated blast-furnace slag (GGBS), known to improve some performance characteristics of concrete, is used as an effective cement replacement to manufacture mortar samples. Here, the influence of curing conditions on the durability of samples including various amounts of GGBS is investigated experimentally and numerically. Twelve high-strength Portland cement CEM I 52.5 N samples were prepared, in which 0%, 45%, 60%, and 80% of cement were substituted by GGBS. In addition, three curing conditions (standard, dry, and cold curing) were applied to the samples. Durability aspects were studied through porosity, permeability, and water absorption. Experimental results indicate that samples cured in standard conditions gave the best performance in comparison to other curing conditions. Furthermore, samples incorporating 45% of GGBS have superior durability properties. Permeability and water absorption were improved by 17% and 18%, respectively, compared to the reference sample. Thereafter, data from capillary suction experiments were used to numerically determine the hydraulic properties based on a Bayesian inversion approach, namely the Markov Chain Monte Carlo method. Finally, the developed numerical model accurately estimates the hydraulic characteristics of mortar samples and greatly matches the measured water inflow over time through the samples.
