Investigating the Properties of Foamed Mixture Lightweight Soil Mixed with Bauxite Tailings as Filler

open access: yesAdvances in Materials Science and Engineering, Volume 2019, Issue 1, 2019., 2019
To make better use of large amounts of discarded bauxite tailings (BTs), a foamed mixture lightweight soil mixed with BTs as filler (FMLSB) was proposed. Using the orthogonal experimental design method, the effects of various contents of cement, BTs, and foam on the fluidity, wet density, unconfined compressive strength, water absorption, and ...

Mechanism of Zinc Corrosion in Accelerated Corrosion Tests

open access: yesMaterials and Corrosion, Volume 76, Issue 8, Page 1106-1119, August 2025.
Real‐time corrosion rate of zinc was measured using electrical resistance sensors. Chloride deposition is the most corrosive phase of the test. Chloride concentration and deposition method affect corrosion throughout the test. Corrosion is accelerated by prolonged wet/dry transitions.

Using Statistical Analysis to Assess Urban Groundwater in Beni Mellal City (Morocco)

open access: yesInternational Journal of Agronomy, Volume 2019, Issue 1, 2019., 2019
The study was carried out in a shallow phreatic aquifer in the piedmont zone between the Atlas Mountains and Tadla plain in Morocco. This study is carried out using physicochemical analyses with statistical analysis (CA and PCA) to show variability of groundwater hydrochemical parameters beneath Beni Mellal city in order to know spatial variability of ...

An Application of near Infrared Spectroscopy to the Study of Carbonate Minerals—Smithsonite, Rhodochrosite, Sphaerocobaltite and Cadmium Smithsonite

open access: yesJournal of Near Infrared Spectroscopy, 2006
Near infrared (NIR) spectroscopy has been applied to the study of selected calcite group minerals including smithsonite, rhodochrosite, sphaerocobaltite and cadmium smithsonite. The isomorphic substitution of calcium in calcite group minerals by divalent cations such as Fe, Cu, Cd, Mn, Mg, Co, Zn is in agreement with variable ...

Study on the Processing Technology of Calamine Calcination by Near‐Infrared Spectroscopy

open access: yesJournal of Spectroscopy, Volume 2019, Issue 1, 2019., 2019
Near‐infrared spectroscopy has been widely used in qualitative and quantitative analysis and online monitoring in the production process of traditional Chinese medicines. The aim was to establish a fast determination model of zinc oxide (ZnO) content in calcined calamine and to explore methods through judging the end point of calamine calcination ...
