“…Based on the aforementioned, such classical methods for assessing the efficiency of the developed geopolymer mixtures require extensive experimental studies to find the optimum content, owing to the complexity of the chemical reactions involved with different parameters. Hence, many scientists have shifted their interest toward adapting systematic optimization methods before conducting the experimental program [14][15][16][17].…”

The feasibility of blending ceramic waste powder (CWP) with blast furnace slag (BFS) to produce geopolymer concrete has seen limited investigation. This study aims to optimize the mixture proportions of CWP-BFS blended geopolymer concrete for superior mechanical and durability characteristics using the best-worst method (BWM) for multi-criteria optimization. The design of the experiments was carried out using the Taguchi method for five factors, each having four levels. The resulting CWP-BFS geopolymer concrete mixtures of the L16 orthogonal array were proportioned using different binder content, BFS replacement percentage, alkaliactivator solution to binder ratio (AAS/B), sodium silicate (SS) to sodium hydroxide (SH) ratio (SS/SH), and SH solution molarity. Test methods included compressive strength and water absorption. The two quality criteria were given equal weights to determine the optimal levels of factors. The method revealed that the optimum mix had a binder content of 450 kg/m 3 , BFS replacement percentage of 60%, AAS/B of 0.5, SS/SH of 1.5, and SH solution molarity of 10 M. Experimental findings endorse the utilization of CWP in geopolymer concrete as a means of alleviating the adverse environmental impact associated with its disposal.

“…Advanced systematic design approaches, including the Taguchi method, have been successfully employed to find the optimum levels of factors [28][29][30]. In construction products, i.e., paste, mortar, and concrete, Fantous and Yahia [31] and Xu et al [32] adopted the Taguchi method to optimize the mixture proportions for superior mechanical performance. While the Taguchi method is reliable in seeking a single optimum performance, it lacks the ability to simultaneously consider various performance characteristics.…”

This study assesses the effect of mix design parameters on the fresh and hardened properties, cost, and carbon footprint of geopolymer mortar made with desert dune fines (DDF) and blast furnace slag (BFS). Taguchi method was employed in designing the experiments. Four factors were considered, each having three levels, leading to a total of nine geopolymer mortar mixes. The factors comprised the DDF replacement percentage, alkali-activator solution to binder ratio (AAS/B), sodium silicate-to-sodium hydroxide ratio (SS/SH), and sodium hydroxide (SH) molarity. Ten performance criteria were evaluated, including the flowability, final setting time, hardened density, 1, 7, and 28-day compressive strengths, water absorption, sorptivity, cost, and carbon footprint. ANOVA was carried out to estimate the contribution of each factor towards the response criteria. Further, TOPSIS analysis was utilized to optimize the mixture proportions of DDF-BFS blended geopolymer mortar. Experimental results showed that up to 25% DDF replacement enhanced the density, strength, and durability of the geopolymers with minor impact on the flowability and setting time. Higher replacement percentages had a detrimental impact on the performance but could still be utilized in specific mortar construction applications. The other factors had more limited contributions to the performance, evidenced by the ANOVA. TOPSIS method revealed the optimum mix to be made with DDF replacement of 25%, AAS/B of 0.5, SS/SH of 1.5, and SH molarity of 10 M. Different multivariable regression models were also developed to predict the fresh and hardened properties of the DDF-BFS geopolymer mortars using the mix design parameters.

Achieving optimum performance of geopolymer mortar intended for structural and repair applications is a complex task with various factors being considered prior to production. This study explores the influence of mix design parameters on the fresh and hardened properties of geopolymer mortar made with treated dune sand (TDS) and granulated blast furnace slag (BFS). A total of nine geopolymer mortar mixtures were designed following the Taguchi method for four factors, each with three levels. These factors included BFS replacement rate by TDS, alkali-activator solution to binder ratio (AAS/B), sodium silicate-to-sodium hydroxide ratio (SS/SH), and sodium hydroxide (SH) molarity. The investigated performance quality criteria were flowability, compressive strength, water permeability, and carbon dioxide footprint. The effect of various factors on the responses was assessed through ANOVA while determining the signal-to-noise (S/N) ratios to seek the optimum proportions of mixtures. Results revealed that a mix made with TDS replacement, AAS/B, SS/SH, and SH molarity of 25%, 0.5, 1.5, and 14 M yielded superior performance.
