Abstract：
Every year, millions of tons of red mud (RDM) are created across the globe. Its storage is a major environmental issue due to its high basicity and tendency for leaching. This material is often kept in dams, necessitating previous attention to the disposal location, as well as monitoring and maintenance during its useful life. As a result, it is critical to develop an industrial solution capable of consuming large quantities of this substance. Many academics have worked for decades to create different cost-effective methods for using RMD. One of the most cost-effective methods is to use RMD in cement manufacture, which is also an effective approach for large-scale RMD recycling. This article gives an overview of the use of RMD in concrete manufacturing. Other researchers\' backgrounds were considered and examined based on fresh characteristics, mechanical properties, durability, microstructure analysis, and environmental impact analysis. The results show that RMD enhanced the mechanical properties and durability of concrete while reducing its fluidity. Furthermore, by integrating 25% of RDM, the environmental consequences of cumulative energy demand (CED), global warming potential (GWP), and major criteria air pollutants (CO, NOX, Pb, and SO2) were minimized. In addition, the review assesses future researcher guidelines for concrete with RDM to improve performance.
摘要：
每年,在全球范围内产生了数百万吨的赤泥（RDM）。由于其高碱度和浸出倾向，其储存是一个主要的环境问题。这种材料通常保存在水坝中，需要事先注意处置地点，以及在其使用寿命期间的监测和维护。因此,开发一种能够消耗大量这种物质的工业解决方案至关重要。几十年来，许多学者一直致力于创造不同的成本效益方法来使用RMD。最具成本效益的方法之一是在水泥制造中使用RMD，这也是大规模RMD回收的有效途径。本文概述了RMD在混凝土制造中的应用。其他研究人员的背景是根据新鲜的特征考虑和检查的，机械性能，耐用性,微观结构分析，和环境影响分析。结果表明，RMD提高了混凝土的力学性能和耐久性，同时降低了其流动性。此外，通过整合25%的RDM，累积能源需求(CED)的环境后果，全球变暖潜势(GWP)和主要标准空气污染物(CO，NOX,Pb,和SO2)被最小化。此外,该综述评估了未来研究人员对RDM的具体指导原则，以提高绩效。
