Unconfined compressive strength (UCS) can be used to assess the applicability of geopolymer binders as ecologically friendly materials for geotechnical projects. Furthermore, soft computing technologies are necessary since experimental research is often challenging, expensive, and time-consuming. This article discusses feasibility performance required predict UCS using a Random Forest (RF) algorithm. The alkali activator studied was sodium hydroxide solution, considered source material ground-granulated blast-furnace slag fly ash. A database with 283 clayey soil samples stabilized determine UCS. split into two sections development RF model: training data set (80%) testing (20%). Several measures, including coefficient determination (R), mean absolute error (MAE), root square (RMSE), were effectiveness model. statistical findings this study demonstrated that reliable model predicting value geopolymer-stabilized soil. based on obtained values RMSE = 0.9815 R2 0.9757 set, respectively, approach showed provide excellent results unknown within ranges examined parameters. Finally, SHapley Additive exPlanations (SHAP) analysis implemented identify most influential inputs quantify their behavior input variables

Iron ore tailings stabilization with alternative alkali-activated cement for dry stacking: mechanical and microstructural insights

Canadian Geotechnical Journal, Год журнала: 2024, Номер 61(4), С. 649 - 667

Upstream tailings dams are high-risk structures that have experienced several failures worldwide, particularly with iron ore (IOT). In this study, new disposal methods/techniques, such as cement-stabilized dry stacking, discussed provide enhanced mechanical behavior while reducing failure risks. Alkali-activated materials used cementing agents due to their and environmental advantages compared ordinary Portland cement. This study evaluates the microstructural of IOT stabilized an alkali-activated cement (AAC) composed two by-products from beneficiation process, metakaolin sodium silicate, tested under plane strain conditions. Simple shear tests analysis were performed. Mixtures produced 0%, 1%, 3%, 5% AAC examine influence variables on strength deformability parameters undrained The mixtures 3% showed greatest impact strength; however, addition 1% was able reduce positive pore-pressure generation. Cementitious bounds evidenced by forming a aluminosilicate hydrate gel. studied effective in stabilizing IOT, even at small contents.

Maintaining and enhancing soil stability for electrical pylon installation is very vital to provide an uninterrupted energy supply. Conventionally, the of maintained using chemical stabilization technique, which has its limitations, not environmentally friendly, may a stable condition in longer term, prone disruption. Therefore, this work, more sustainable approach suggested where bio-mediated technique microbes from biological degradations vegetables are used integrate with polyethylene terephthalate (PET) plastic waste as stabilizer. The findings triaxial shear test showed that treated enhanced soil's resistance shearing forces by 33% due bridging effect interlocking. combination 20% fermented grout liquid 1% PET improved cohesion significantly. slope also proved additions could improve factor safety (FOS) up 81.47% exceed minimum requirement design compared untreated slope. results influence different variations addition effective method engineering properties
