“…In this investigation, the preparation processes of stabilized soil specimens can comply with the method mentioned in Ref. [2]. Initially, the dried soil (with a constant temperature of 105°C for more than 24 h) was crushed down by the hammer and passed through a 2 mm sieve.…”

“…All the mixing procedures were finished, and then the appropriate curing measure was taken to achieve moisture equilibrium. According to the method mentioned in the relevant researches [2,6,9,11], the soil-additive mixtures were kept in a closed container and stored at a temperature of 20°C ± 2°C for 24 h to satisfy the condition of moisture equilibrium. After that, the mixtures were placed into a standard mould.…”

“…Soil stabilization technique is a common method for the modification and improvement of the various properties of expansive soil [1]. Expansive soil generally poses a volume change behavior due to the variation of moisture content in the soil [2,3]. erefore, this particular property can easily bring out serious problems to several engineering constructions, such as foundation, road, embankment, and railway [1][2][3].…”

“…Expansive soil generally poses a volume change behavior due to the variation of moisture content in the soil [2,3]. erefore, this particular property can easily bring out serious problems to several engineering constructions, such as foundation, road, embankment, and railway [1][2][3]. Previous investigations by many researchers have observed that the soil stabilization technique produced a significant improvement in terms of geotechnical properties, which include swelling-shrinkage, compaction, plasticity, compressibility, and strength properties [4][5][6][7].…”

“…In addition, the above studies have analyzed the effect of cyclic wetting-drying and cyclic freeze-thaw phenomena on stabilized soil. In practical engineering, the stabilized soils are not only subjected to static loading [2,4,7,15,17], wettingdrying cycles [10,19,20], and freeze-thaw cycles [21] but also subjected to impact loading [27]. For instance, in the construction of national defense engineering, the geomaterials of stabilized soil were usually subjected to strong dynamic loading, such as impacting and explosion [28].…”

The purpose of this article is to evaluate the influence of basalt fiber content on the static-dynamic mechanical properties and microstructure of cement-fly ash-stabilized soil. The optimum mixed contents of cement and fly ash were obtained from the results of a series of physical and mechanical experiments. Based on the optimum mixed contents of cement and fly ash, the static-dynamic mechanical performances and microstructure of cement-fly ash-stabilized soil reinforced with basalt fiber were studied by means of the unconfined compression test, dynamic compression test (namely, SHPB test), and SEM test. The results demonstrated that the addition of basalt fiber in cement-fly ash-stabilized soil significantly enhanced the static-dynamic mechanical properties of stabilized soil. With basalt fiber content varying from 0% to 1.2%, the unconfined compressive strength, dynamic compressive strength, dynamic increase factor, and specific energy absorption of stabilized soil showed an upward trend first and a downward trend subsequently. The unconfined compressive strength, dynamic compressive strength, and energy absorption ability have a maximum improvement under the optimum basalt fiber content of 0.6%. In addition, the inclusion of basalt fiber can change the failure pattern of cement-fly ash-stabilized soil. The fractal dimension of broken fragments decreased gradually with the increasing basalt fiber content and increased correspondingly with the increasing impact loading pressure. With the basalt fiber content of 0.6%, a stable internal space structure produced inside stabilized soil. However, there are many fiber-fiber weak interfaces that appeared inside stabilized soil under the basalt fiber content of 1.2%. The microstructural observations can be considered as the good interpretations to verify the macroscopic mechanical characteristics.

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.
