“…As a result, more than 20% RMD substitution reduces the concrete solid mass’s compressive quality and stiffness [ 57 ]. Increases the load-bearing capability of RMD-based concrete samples by up to 10% by increasing the RMD component [ 58 ]. The self-compacting concrete (SCC) mixes created with RMD inclusion showed equivalent CMS to the control at 28 days, according to the findings.…”

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.

“…Red mud also possesses significant pozzolanic characteristics due to its high concentrations of alumina and silica [20]. Calcium hydroxide reacts with silica in the red mud when the concrete is wet, enhancing the strength of the concrete [21]. The inclusion of aluminates and ferrites in cement materials enhances the reactivity of silica [22].…”

The purpose of this study is to assess the effect of red mud in compensating for ordinaryPortland cement (OPC) in concrete manufacture. One set of 30:70, 40:60, 50:50, 60:40, and 70:30 in weight proportions red mud (RM) and fly ash (FA) was used to make this geopolymer concrete, whereas the other set of geopolymer concrete was prepared with the same proportions with red mud and ground granular blast furnace slag (GGBFS). The high alkalinity of red mud, a byproduct of alumina production in bauxite processing, has a substantial environmental impact and is useful as a binder for geopolymer concrete. When compared to standard Portland cement concrete specimens, the increases in strength of both sets of red mud-based binary geopolymer concrete specimens were reported to be 21%, 24%, 25%, and 15%, 16% 17% and 18% 11% 7% in ambient curing and 42% 45% 50%, 45% 31% 33% and 37% 27% 24%, respectively. Red mudground granular blast furnace slag based binary geopolymer concrete has superior values than the other mix. Compressive strength of geopolymer concrete may reach 31.21 MPa, suggesting it can be utilized as an alternative to cement concrete components in constructions.

“…Considering construction material based on red mud, this material has been investigated on special cement production [104][105][106][107][108]. Using wastes or secondary raw materials in construction is essential to face the diminution of primary raw materials and promote the circular economy [109].…”

Red Mud from the Aluminium Industry: Production, Characteristics, and Alternative Applications in Construction Materials—A Review

et al. 2021

View full text Add to dashboard Cite

About 120 million tons of red mud is produced worldwide each year. Due to its high basicity and potential leaching, its storage is a critical environmental problem. This material is typically stored in dams, which demands prior care of the disposal area and includes monitoring and maintenance throughout its useful life. Consequently, it is crucial to figure out an industrial solution able to consumes large volumes of this material. At this moment, there are several studies, the majority in metallurgical procedures, building materials, and in the chemical industry, discussing how to reuse red mud. This paper provides a review of the aluminium process, including metal importance, its global production, and the environmental impact due to its manufacture process. It presents a review of the potential application of red mud showing its overall generation, some relevant characterisation results collected from the literature, and its utilisation in diverse areas of engineering. The study aimed to highlight applications where red mud characteristics may be favourable.
