This research studies the properties of mortars incorporating waste materials including red mud (RM), ground granulated blast furnace slag (GGBFS), and electric arc dust (EAFD). Ordinary Portland cement (OPC) was partially replaced with equal contents RM, GGBFS, EAFD at different ratios by weight (0, 5, 10, 15, 20, 30, 40, 50%). Slump, compressive strength, splitting tensile electrical resistiv...

In this paper, Bayer red mud and ground granulated blast furnace slag were formed into three different ratios (7:3, 5:5 3:7) of alkali-activated cementitious materials (AASR) using a water glass solution as the alkali activator. By studying compressive strength content, effect content on mechanical properties AASR was analyzed. The influence mechanism revealed by variation micro-porosity, conne...

Bauxite residue (red mud) generated during alumina production is a highly alkaline solid waste. The red mud mainly stored on land, but it can cause harm to the surrounding environment and human health. transformation of into soil feasible method for large-scale disposal mud, alkali removal key process that controls soil. In this study, calcification dealkalization with small particle size was c...

Experiments were conducted to investigate the mineral phase transformation technology of high-iron red mud, effectively extracting valuable iron minerals and reducing hazards associated with mud stockpiling storage. A magnetic concentrate an grade 55.84% recovery 93.75% could be obtained at a roasting temperature 560 °C, time 15 min, CO concentration 20% total gas flow 500 mL/min. combination X...

The excessive production of bauxite residue (red mud) in the Bayer process is one major challenges amongst alumina producers. Pedersen known as a combination smelting reduction and leaching treatment produced slag for production, also produces an inert (grey mud), which more suitable further processing compared to red mud. This paper describes life cycle assessment two processes, current commer...

Sustainable utilization of the bauxite residue (red mud) generated from alumina refining has recently increased due to environmental concerns because its high alkalinity and problematic pollutants when placed in landfills. This paper attempts review recent research findings utilizing red mud as a road material pavement structures literature, including bases asphalt mixtures. Previous laboratory...
