“…Thus, employing SCMs as partial substitutes for clinkers in cement, such as powdered granulated blast furnace slag, fly ash, volcanic ash, metakaolin, and silica fume, can significantly reduce CO 2 emissions and amount of garbage deposited in lake. This makes better use of industrial waste and reduces the amount of clinker in cement, lowering both the use of natural resources and the cost of cement (Awol, 2011;Biswas & Rai, 2020;Deboucha et al, 2017;Prakash et al, 2022;Taffese, 2018;Yang et al, 2013;Yening et al, 2019). Furthermore, SCMs such as ground granulated blast furnace slag, metakaolin, silica fume, and fly ash consumption as a portion of binders for concrete have been increasing all over the world, particularly in the production of high-performance and high-strength concrete.…”

The current study aimed to investigate the influence of the expired hardened cement blended with ground granulated blast furnace slag on the bond, microstructure, and durability of high-strength concrete (HSC). Five concrete mixes are prepared; the first mix is taken as a control, and the remaining four mixes are used as experimental blends. HSC characteristics are evaluated by compressive, flexural, splitting tensile, bond, and durability tests. Furthermore, the ultrasonic pulse velocity and microstructural characteristics tests are carried out to check concrete quality. The synergistic action of blends (expired harden cement with GGBS) on the strength test results was found to increase with an increase in blends up to 20%. The durability result reveals that HSC was found to be impermeable under aggressive conditions. The microstructural characteristics achieved in the current investigation explain the above strength, bond, and durability performance of these mixes. The whole performance of blends in HSC is adequate for industrial use.

“…Therefore, by minimizing the negative impacts of concrete on the environment, CI can achieve sustainability. This can be achieved by replacing partial or all the concrete ingredients such as aggregates and cement with industrial waste (Johari et al, 2009;Majhi & Nayak, 2019;Prakash et al, 2022;Shariq et al, 2013).…”

“…Some scholars have improved the mechanical properties and durability of concrete by mixing fiber and mineral materials [ 42 , 43 , 44 , 45 ]. Mosavinejad et al [ 42 ] prepared ultrahigh-performance concrete with a high content of silica fume and short-cut polyvinyl alcohol fibers and concluded that, for compressive strength, the optimum ratio of silica fume to cement is 0.3, a further increase in silica fume content leads to a decrease in compressive strength, and the incorporation of PVA fibers reduces the diffusion and penetration of chloride ions.…”

Satnam et al [ 44 ] found that mixing scrap tire rubber and silica fume can improve the impact resistance of concrete.…”

Silica-fume–polyvinyl-alcohol-fiber-reinforced concrete (SPRC) is a green and environmentally friendly composite material incorporating silica fume and polyvinyl alcohol fiber into concrete. To study the impact resistance of SPRC, compressive-strength and drop hammer impact tests were conducted on SPRC with different silica-fume and polyvinyl-alcohol-fiber contents. The mechanical and impact resistance properties of the SPRC were comprehensively analyzed in terms of the compressive strength, ductility ratio and impact-energy-dissipation variation. Based on the impact resistance of the SPRC, the impact life of SPRC with different failure probabilities was predicted by incorporating the Weibull distribution model, and an impact damage evolution equation for SPRC was established. The impact life of SPRC under the action of silica-fume content, polyvinyl-alcohol-fiber content and failure probability was analyzed in depth by the response surface method (RSM). The research results show that, when the content of silica fume is 10% and the content of polyvinyl alcohol fiber is 1%, the compressive strength and impact resistance of SPRC are the best. The RSM response model can effectively predict and describe the impact life of SPRC specimens under the action of three factors.

“…In the underwater zone, chlorides from chlorine disinfectants used for water purification may contribute to deterioration [ 3 , 4 , 5 , 6 , 7 , 8 ]. This raises a concern since inside the water treatment facilities that have continuous freshwater environment, chloride penetration into concrete leads to rebar corrosion in the reinforced concrete structure [ 9 , 10 , 11 , 12 ]. The atmospheric zone is vulnerable to carbonation.…”

This study seeks to analyze how the degree of carbonation and the application of waterproofing and anticorrosive materials affect carbonation in water reservoirs among the water treatment facilities managed by the Seoul Metropolitan Government. To guarantee similarity of the experimental group, 42 highly similar water reservoirs were selected from among the water supply reservoirs currently in operation in Seoul. On-site carbonation assessments were performed in order to derive the carbonation rate coefficients. In the water reservoirs with applied waterproofing and anticorrosive materials immediately after public service, the upper and lower limits were D = 1.13 and D = 0.29, respectively, whereas those of the water reservoir applied with waterproofing and anticorrosive materials after 15 years of service life were D = 1.89 and D = 0.94, respectively. The comparative analysis showed that the rate of reduction in the carbonation rate was about 10.4% to 16.8% in the water reservoirs applied with waterproofing and anticorrosive methods after 15 years of service life. However, reduction in the carbonation rate was about 46.4% to 74.3% in the water reservoirs applied with waterproofing and anticorrosive methods at the initial stage of service life. It was confirmed that the early application of waterproofing and anticorrosive materials is effective in suppressing carbonation of concrete water reservoir structures.
