“…Various chemical agents, such as lime, cement, and pozzolana, as well as industrial waste, such as fly ash (FA) and metakaolin (MK), are utilized for stabilization [2][3][4][5]. Marble dust, pumice powder, iron, and chrome slags are also used to stabilize soft clayey soils [6,7]. Lime and cement are the most widely used binders in chemical soil stabilization [8].…”

Soft soils require particular consideration when designing civil engineering structures due to their high compressibility, low shear strength, and permeability. Using chemical additives and geopolymers to stabilize soft soils is a practical approach to improve their engineering properties. The objective of the study was to explore the use of conventional stabilizers alongside metakaolin-based geopolymers. This study also aimed to investigate the compaction characteristics, mechanical strength, shear behavior, and microstructure of stabilized soft soil. The compaction test was carried out using various amounts of cement (6%, 8%, and 10%) and metakaolin (3%, 5%, and 7%) based on the dry weight of the soil. Cement, lime, and geopolymer were added to the soft soil at 15% of the dry weight of the soil for triaxial shear tests. The compaction test results indicated that the stabilized soil exhibited the highest maximum dry density at 8% cement content. Adding metakaolin (MK) to the cement-modified soil decreased the maximum dry density, smoothed the compaction curve, and increased the optimum moisture content. The unconfined compressive strength (UCS) test revealed that cement-stabilized soil had the highest yield stress, while adding MK to the cement-modified soil reduced the yield stress after 7 days of curing. Compared to untreated soft soil, there was a significant increase in shear strength parameters for cement-, metakaolin-, and lime-stabilized soil. This study demonstrates that adding chemical additives and geopolymers can improve the soft soil’s compaction characteristics, mechanical strength, and shear strength parameters.

“…Different techniques such as polymerization have been proposed and used to address the mentioned issues. Geo-polymerization is a trending technology for making use of by-products such as fly ash, bottom ash, blast furnace slag, kiln dust, marble and pumice powder, agricultural wastes, and many others (Bhurtel & Eisazadeh, 2020;Çadir & Vekli, 2022;Fauzi et al, 2013;Jamsawang et al, 2017;, as well as for the halting of toxic metals in the management process of hazardous wastes. It is considered a cost-friendly alternative because of its decreased impact on landfills and the reduction of about 80% CO2 emissions compared to the use of ordinary Portland cement (Arrieta Baldovino et al, 2020).…”

<p>Expansive soils pose a danger to the foundations of engineering structures due to their poor engineering properties. These soils are usually treated using mechanical techniques, and chemical stabilizers. However, the production of these chemicals is not friendly to the environment, thus a need to adopt waste materials. Therefore, this research investigated the efficacy of utilizing waste crushed glass to alter the engineering properties of the soil. The study's objectives were achieved by conducting experiments on non-stabilized soil, and waste glass powder (WGP) stabilized soil in the percentages of 3, 5, 7, and 9% of dry weight of the soil. The findings showed that adding glass powder to subgrade soil strengthens it and reduces its susceptibility to volume change. The highest compressive strength was obtained after mixing 7% waste glass powder with the soil, and beyond that, the strength reduced. The study found that the inclusion of 7% waste glass powder content is suitable for the stabilization of the soil possessing properties similar to the ones in the study area.</p>
