Life cycle assessment (LCA) is used to quantitatively analyze the energy consumption and environmental impact of primary aluminum production in China, United States, Europe, as well global average. The results indicate that electricity fuel contribute more than 60% bauxite mining; steam greatest contributor alumina by Bayer process, with a result exceeding 35%; contributes >50% electrolysis. China 1.2 times contributions three stages total process are, descending order, electrolysis (64.33%), (33.09%), mining (2.58%). If proportion thermal power source structure reduced from 0%, contribution will decrease 38% 2%, 73%. Therefore, conservation emissions reduction can be realized through optimization generation structure, adoption clean production, improvement heat utilization rate processes.

To achieve the efficient utilization of magnesium slag, this study investigates use fly ash, and metakaolin as partial substitutes for cement in cementitious materials. The reactivity these materials is assessed based on compressive strength mortar. response surface methodology employed to explore influence material proportions performance mechanisms underlying development composite system are examined through XRD, SEM, TG-DTG, BET analyses. Additionally, effect slag drying shrinkage properties mortar studied. experimental results indicate that exhibits low cannot be used alone an active admixture. optimal proportion metakaolin, 10:10:10:70, achieving over 80% pure approximately 1.5 times containing 30% slag. Furthermore, helps mitigate volume caused by Therefore, can facilitate comprehensive construction sector, reducing its negative impact ecological environment.
