Triaxial behavior and microstructural insights of loose sandy soil stabilized with alkali activated slag

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 28, 2025

This study investigates the mechanical and microstructural properties of loose sandy soil stabilized with alkali-activated Ground Granulated Blast Furnace Slag (GGBFS). To examine effects varying GGBFS contents, curing times, confining pressures on behavior, undrained triaxial unconfined compressive strength (UCS) tests were conducted. Microstructural analyses using FE-SEM, EDX, FTIR performed to elucidate nature development cementation. The results behavior demonstrate that even limited content (1–6%), treated samples exhibited significant improvements in strength, stiffness, energy absorption, underscoring efficiency as a stabilizer. Moreover, parameters from revealed nearly constant internal friction angle increasing duration, while cohesion showed remarkable enhancement. A strong linear correlation between UCS was also identified, enabling cost-effective estimation shear parameters. These findings highlight potential for improving granular soils, offering practical implications sustainable geotechnical applications, particularly road construction.

Effects of Industrial and Agricultural Recycled Waste Enhanced with Lime Utilisation in Stabilising Kaolinitic Soil

International Journal of Sustainable Construction Engineering Technology, Год журнала: 2023, Номер 14(4)

Опубликована: Окт. 15, 2023

Soft kaolin clay is a problematic soils encountered in various construction projects that lead to the implementation of soil stabilisation. On other side, massive production industrial and agricultural waste currently presents critical problem for environment. However, utilisation wastes altering characteristics kaolinitic can be considered as an ideal solution enhance characterisation field construction. Therefore, this study examines alterations engineering properties soft by utilising silica fume by-product eggshell ash enhanced with lime use. To assess impact fume, ash, on soil, series laboratory experiments containing Atterberg limits, specific gravity, compaction test, unconfined compression X-ray fluorescence, diffraction, sieve analysis, emission scanning electron microscope carried out. In study, 2%, 4% 6% 3%, 9% optimal combination SF, ESA are usedand were cured 1, 7, 14 30 days. The results present utilization alter reducing consistency linearshrinkage, maximum dry density, while increasing value shrinkage limit, optimum moisture content. terms strength improvement, highest was recorded when treated four (4) different days curing improvement 81.03%, 82.46%, 88.49% 88.74%. concludes use persistently open way economical sustainable materials improving soil.
