“…The density of geopolymer made with quarry dust and waste glass was investigated [116], where the addition of geopolymer cement to the soil was able to increase the maximum dry density of the final mixture. In a separate work on the bulk density of fly ash geopolymer [44], the highest obtained value was related to samples made with NaOH (12 M) and sodium silicate, which were cured for 1 h (Figure 11).…”

Carbon footprint reduction of paving materials could be explored through recycling mining by-products into different applications, which will preserve natural resources and decrease environmental issues. One possible approach is to reuse quarry dust and mining ore waste as precursors in geopolymer applications. geopolymers are mineral polymers rich in aluminosilicates with an amorphous to a semi-crystalline three-dimensional structure. The current review aims to summarize the studies conducted during the past decade on geopolymers containing quarry dust and mine tailings. The first section discusses various precursors used for geopolymer cement production such as metakaolin, ground granulated blast furnace slag (GGBFS), fly ash, and quarry/mining ore wastes including silt, tungsten, vanadium, copper, gold, zinc, marble, iron, basalt, and lithium. Different calcination treatments and curing conditions have been summarized. In some cases, the precursors are required to be calcined to increase their reactivity. Both ambient temperature and elevated temperature curing conditions have been summarized. Less attention has been paid to room temperature curing, which is necessary for field and industrial implementations. Engineering properties such as compressive strength, density, durability and acid resistance, water absorption and abrasion of geopolymers containing mining waste were reviewed. One of the main barriers preventing the widespread use of waste powders, in addition to economic aspects, in geopolymers could be due to their unstable chemical structure. This was shown through extensive leachate of Na+ or K+ cations in geopolymer structures. The review of over 100 articles indicated the need for further research on different aspects of quarry waste geopolymer productions before its full industrial implementation.

“…The physical action of the QD particles resulted in physical modification through imparting an improved gradation and coarse-granular nature to the soil. This resulted in a more intense interlocking of the particles with higher shear resistance, which is a known characteristic of QD particles as per previous studies [14,87]. The chemical actions which modified the soil microstructure were due to hydration and pozzolanic reactions of the cement and additives particles (SDA and QD), which are pozzolanic materials.…”

“…The geomaterials are categorized into traditional and non-traditional additives. Some of the traditional additives include cement, lime, fly ash, et cetera while the nontraditional ones include cement kiln dust (CKD), sawdust ash (SDA), mine tailings, coal bottom ash, bagasse ash, sulphonated oil and others [12][13][14][15].…”

In this study, variable returns to scale (VRS) data envelopment analysis was integrated into the Taguchi approach to optimize ternary additives for expansive soil enhancement. The ternary additives selected were sawdust ash (SDA), quarry dust (QD) and ordinary Portland cement (OPC). The additives were set as the input variables while multiple responses obtained from the experiments performed with the Taguchi orthogonal array were set as the output variables. Each row in the orthogonal array were defined as a decision making unit (DMU) in the optimization process and output-oriented VRS model was used to obtain the efficiency score for each DMU. Next, benevolent formulation was utilized to obtain the multipliers for the inputs and outputs which were subsequently used to determine the cross efficiency scores for each DMU. The cross-efficiency scores were used to construct the cross-efficiency matrix. Thereafter, the mean cross-efficiency score (MCES) was determined for each DMU. Parameter level that maximizes the MCES was chosen as the optimal level for that parameter. Optimum combination of additives was found at A6 B2 C3. Lastly, confirmatory experiments performed by blending the soil with the optimum combination of additives showed the effectiveness of this method in the enhancement of expansive soil properties.

“…The coarse fraction effectively improves the angle of friction, giving the soil a higher shear resistance. Results of other studies have shown that QD possess a high angle of friction and effectively modifies the physical structure of soils with attendant improvement in mechanical strength 80,81 …”

This present study optimizes multiadditives for the improvement of the properties of expansive soil by integrating min‐max fuzzy goal programming model, a variant of fuzzy goal programming, into Taguchi optimization method. The multiadditives, which included ordinary Portland cement (OPC), quarry dust (QD), and sawdust ash (SDA), had various levels assigned to them in the Taguchi designed experiment, and they were all added by air‐dried weight of the expansive soil. Responses that included differential free swell, California bearing ratio, and unconfined compressive strength were determined using the Taguchi designed experiment. Concurrent analysis of the data obtained from the responses was performed using the min‐max fuzzy goal programming and the optimum combinations of additives that resulted in the significant improvement of the soils were obtained at 20% SDA, 20% QD, and 8% OPC. In addition, scanning electron micrograph analysis for the expansive soil that was combined with the optimum combination of additives showed cementitious compound formation in the soil‐additives mixtures and this confirmed lucidly that min‐max fuzzy goal programming can be integrated in Taguchi method to optimize additives for the improvement of expansive soil properties.
