“…Experiments were designed by Taguchi technique using MINITAB 17 software. Design of experiments in the form of orthogonal array (OA) has been given in Table 2, in which each row signifies experimental conditions with alternative additive dosage [26], [27]. Comprehensive details on Taguchi technique can be found in notable books of pioneer authors [28]- [30].…”

Although many techniques are available for the evaluation of soil parameters, but a quick and efficient method is always welcome. To avoid the hassle calculation and tedious procedures of testing; practitioners seek a fast method for site implementation of laboratory results. In the recent era of development and technology, it has been necessary to adopt the advanced techniques to evaluate the geotechnical parameters. In the present study, correlations between geophysical and compaction tests results have been derived. Eggshell powder (ESP), a waste material along with sodium chloride (NaCl) and polypropylene fiber (PPF) was used to stabilize the soil. Design of experiments was done by Taguchi technique using Minitab 17 software. A series of non-destructive geophysical tests i.e., Ultrasonic pulse velocity (UPV) and Electrical resistivity (Re) tests was carried out on 21 days aged soil specimens. Not only software based analytical results showed ESP as the dominating factor for attaining improvement in packing of soil particles and make soil resistive but also the results confirmed the same. UPV of the stabilized soil was found increased up to 69%-122% with respect to an increase in dry density of about 1.16%-1.74%. The utility of the present study can be found in places where dense soil and electric resistive properties meets such as transmission lines and railway electric poles etc. and for the purpose seismic and resistivity mapping methods can be used

“…UCS based freezethaw applied (10 Cycles) samples were taken under physicochemical testing of plastic soil. Samples for pH test were prepared using the method as suggested in [30][31] which implicates mixing the solids with deionized water (1:5 :: solid:water), periodically agitating samples, and then testing with a multifunction pH meter; Orion 5 Star, Thermo Scientific (Fig. 1) confirming to IS:2720 (Part XXVI)-1987 after 1 hour.…”

Generation of waste from the various industries causes harmful impact to environment if there has no safe management for their disposal or reuse. The construction industries have ability to reuse or utilize different types of solid wastes. The waste from poultry farms in the form of eggshell also cause problems to the environment and need some utilization. The eggshell powder (ESP) is enriched with natural lime; therefore, it can be used for soil stabilization. In the present paper, eggshell powder was used along with sodium chloride (NaCl) and polypropylene fiber (PPF) to study their influence on physicochemical properties of soil. The soil samples were subjected to ten cycles of freeze-thaw before examining the pH of respective sample. Eggshell powder (3%, 6% and 9%), sodium chloride (2%, 4% and 6%) and polypropylene fiber (0.05%, 0.1% and 0.15%) were used and design of experiments was developed using Taguchi technique. Results showed that inclusion of these materials had significant effect on the pH and unconfined compressive strength of subjected soil against harsh environmental conditions, although the relation between pH and UCS was found non-linear.

“…A possible reason for the improvement in the soil parameters from using ionic soil stabilizers was the cation exchange between the stabilizer and the soil minerals. Kumar and Soni (2019) found that the pH of clayey silt is directly proportional to the UCS value and that the high calcium content of eggshell triggers the UCS up to a certain extent. Fibers in a range of (0.10%) improved the strength and compressibility characteristics of expansive soil (Kumar and Jain, 2015;Kumar and Jain, 2017).…”

Lime and cement are quite compatible for stabilizing clayey soils; changes in a thermal regime may inversely affect the advantages of stabilized soil. The present study interprets changes in the mechanical behaviour of frozen and unfrozen Himalayan soil samples through an unconfined compressive strength test. The soil was treated with ground eggshell powder (3%-9%) and alkali activator (Sodium chloride) (2%-6%); it was reinforced with arbitrarily distributed polypropylene fibers (0.05%-0.15%). Standard 7, 14 and 21-day-old soil specimens were tested in unfrozen conditions, while fresh 21-day-old soil specimens were tested after 3, 5 and 10 freeze-thaw cycles. The design of the experiments was based on the Taguchi technique and arranged in an orthogonal array. The results of the research clearly show that poultry waste (eggshell powder) and alkaline soil stabilizer improved the strength behaviour of the subject soil. On the other hand, the polypropylene fibers played an important role in changing the brittle behaviour of the stabilized soil to ductile behaviour. The sudden collapse of a structure may be avoided by using polypropylene fibers. Al-Swaidani, A. -Hammoud, I. -Meziab, A.
