“…They conclude that strength was similar to the reference mix at 15% cement replacement. Similar decrement in strength for increment in the content of red mud [30][31][32][33][34]. Similar findings were also reported by other researcher [35][36][37][38][39].…”

Concrete is an essential construction material and major component of concrete is cement. There is a huge amount of carbon dioxide emission into the atmosphere during manufacturing process of cement which has negative impact on the environment. Thus it become necessary to discover a substitute material for cement in concrete. Rapid industrialization generates a significant quantity of waste material which are causing negative effect on environment. These wastes can be a replacement for traditional material which are used in concrete like cement or fine aggregate. Red mud is waste material which generated from bauxite ore at the time of production of aluminium by the Bayer process. In this review paper, the effort is made to present the properties of concrete with red mud after studying several research papers. This paper discusses the properties of red mud concrete such as workability, compressive strength, split tensile strength, flexural strength, water absorption and modulus of elasticity. This paper shows the feasibility of partial substitution of cement in concrete by red mud. The study shows that incorporating red mud resulted increase in strengths of concrete such as compressive, split tensile and flexural strength. The water absorption of concrete decrease as increase in red mud content, it can be established that there is a possibility for using red mud in concrete as a binder ingredient for sustainable construction.

“…Similar results also found by Bishetti and Pammar [2] tabulated below in Table 1. Tang et al [31] examined the slump flow of selfcompacting concrete (SCC) utilizing red mud as substitute of cement. They observed that diameters of slump flow ranged between 580-630 mm.…”

“…The required superplasticizer dosage to reach this reference flow is shown in Figure 8. Based on the literature, a decrease in workability or increase in superplasticizer demand was expected for the mortars including the SCM (Ribeiro et al, 2010;Tang et al, 2019). Cocalcination with kaolinite did not lower the average superplasticizer requirement, but the variation with the BR source on the result was significantly reduced.…”

“…The cement hydration reactions are accelerated by the alkalinity of BR coming from the residual sodium from the Bayer process, lowering the setting time of mortars and concrete (Ribeiro et al, 2010;Serdar et al, 2017;Romano et al, 2018;Danner and Justnes 2020). The workability is negatively influenced by the addition of BR due to its soluble sodium content and fineness, which increase the superplasticizer need for concrete significantly compared to a reference concrete with fly ash as SCM (Tang et al, 2019). The environmental compatibility and mobility of heavy metals in cementitious products made with BR is not widely published, although BR is known to contain potentially hazardous elements such as Cr, As, or V (Evans 2016;IAI 2020).…”

Co-Calcination of Bauxite Residue With Kaolinite in Pursuit of a Robust and High-Quality Supplementary Cementitious Material

The present article investigates the potential of co-calcination with kaolinite as a sector-wide solution for the transformation of bauxite residue into an effective supplementary cementitious material (SCM). Bauxite residues from eight alumina refineries were co-calcined with 30 wt% of kaolinite at 750°C. SCMs with moderately high reactivities were obtained. Mortars with 30 wt% replacement of Portland cement (CEM I) by co-calcined bauxite residue had relative strengths of 73 ± 4%, 87 ± 4%, and 88 ± 2% after 2, 7, and 28 days compared to a CEM I reference mortar. The reactivity and contribution to strength development were shown to scale linearly with the kaolinite dosage. Most bauxite residues require only 20 wt% substitution by kaolinite to reach the reactivity and performance targets. Co-calcination reduced the mobility of heavy metals significantly. The negative effect on the workability that some BRs with higher content of free sodium exhibited was mitigated by co-calcination. This positive effect was also observed after calcination with 10 and 20 wt% of kaolinite. The same was found for the positive effect on the leaching of heavy metals. The inherent reactivity of the bauxite residue mainly stemmed from the desilication products such as sodalite and cancrinite. During co-calcination, the sodium-containing phases reacted with kaolinite, delivering a supplementary cementitious material with high reactivity and low free-sodium content.

“…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.
