“…4. [26,37]. The single combination mixes of MS-1, MK-1, and CDW-1, as noted from the results, have a higher compressive strength than the other mixes, A-0, MS-0, MS-2, MS-3, MK-0, MK-2, MK-3, CDW-0, CDW-2, and CDW-3.…”

“…Though SF does not sufficiently exhibit the ability to hold alkalis in its hydration products, ternary mixtures with FA and SF have shown greater ability to bind and hold alkalis by [8,35]. Vignesh and Rahim [37] studied about a stable and high strength quaternary binder system consists of Ground Granulated Blast Furnace Slag (GGBS), Metakaolin and lime powder. They reported a highest strength of 54.13 MPa for high concentration of GGBS compared to the other materials.…”

“…For varying binder proportions in a ternary mixture, the first stage yielded the silica fume concentrations in binary mixes with the highest strengths [32][33][34][35][36][37]. According to the results, ternary blends always created almost similar strength combinations than the binary mixtures of OPC and SF when the replacement quantity was appropriately selected [36].…”

“…There also exist potential challenges from dissolved ions as indicated by the ion penetration and diffusive mass transfer [48][49][50]. Even though the corrosion studies deals only with the surface chemistry, the resulting changes can be efficiently demarcated by morphological studies [37][38]49].…”

Recyclable Pozzolanic materials (RPM) derived from wastes are increasingly used in mortar and concrete for a number of purposes, chief among them being the reduction of cement quantity, which lowers construction costs as well as carbon footprint. Among these, the most often used mixture ingredients in concrete are fly ash (FA), rice husk ash (RHA), palm oil fuel ash (POFA), granulated slag (GS), silica fume (SF), construction debris waste powder (CDW), and calcined clay (CC). Recent studies reveal that they are reasonable to impart mechanical strength when applied individually; however, their combined effects are not extensively investigated due to the characteristic conflicts existing in their elemental composition and the resulting pozzolanic activities. We present a comprehensive evaluation of durability and strength properties of different combinations of binary and ternary replacements of specific pozzolanic components in varying amounts (5%, 10%, 15%, and 20%). These combinations were so chosen as to provide a compensatory effect on the apparent binding properties based on the difference in their geometry and composition. The results indicate that 5% of the ternary combination had good corrosion resistance and durability, whereas 10% of the single mode, 5% of the binary mode, and 5% of the ternary mode have high mechanical properties, durability, and resistance to corrosion. These insightful findings show that use of optimized mixtures of composite pozzolanic materials can improve the mechanical properties of concrete mixes by compensating each other for their intrinsic limitations, thereby ensuring higher sustainability towards green concrete applications.

“…Trial experiments were performed to identify the control factors and their levels in the Taguchi technique. According to ASTM C109 (40), mortar cube compressive strength was measured from nine trail mixes and an optimal mix designed using Taguchi's experimental design. From the control factors listed in Table 3, the main effects of S/N ratios were determined based on the "Larger is Better" condition (as depicted in Figure 4) bestowed by Taguchi, where the compressive strength is higher for the optimized mix.…”

In this study, a novel technique for producing synthetic aggregates using industrial by-products was experimentally investigated. Taguchi method is used to identify the optimum mix design proportion to develop durable synthetic aggregates. For this, different combinations of quaternary binders including ordinary Portland cement, ground granulated blast furnace slag, metakaolin, and lime powder was used. The obtained results revealed that the synthetic aggregates prepared with optimized mortar mix enhanced the compressive strength by 5.9%. Then the performance of synthetic aggregates was evaluated based on their mechanical and durability properties. Microstructural properties of the produced aggregates were examined. The results showed that optimum mix is highly effective than control mix. The manufactured synthetic aggregates are in accordance with the ASTM C 330 standard requirements. Therefore, our study contributes to the advancement in the sustainability by developing a method for producing synthetic aggregates from industrial byproducts.
