“…Then, they concluded that it was a suitable way to consume those industrial solid wastes, as the sulfoaluminate cement products are cheaper than Portland cement due to their low material costs, smaller pre-treatment costs, and reduced calcination temperature [128]. Likewise, Cambek and other authors concluded in their study that a mixture of red mud, a sulfate-rich/high-lime fly ash, and desulfogypsum is possible as raw materials in clinkers because the cement produced showed better mechanical performances than the reference sample [129]. Wang and his team highlighted that sometimes alkalinity avoids the large-scale utilisation of red mud in cement production.…”

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.

“…Lima and Callao cities account for 66% of the cars present in the whole Perú (MTC, 2018), therefore Ba concentration found may be related to this activity. Ca is considered as an indicator of cement production (Canbek et al, 2020), and their presence may be ascribed to release from local construction/demolition activities in form of waste and dust resuspension.…”

“…The main clinker phases in CSACs are ye’elimite, Ca 4 (AlO 2 ) 6 SO 4 , belite and calcium sulfate CaSO 4 [ 44 ]. Since ye’elimite rapidly hydrates, it compensates for the loss in early-age strength in belitic clinkers [ 46 ]. As ye’elimite dissolves it enables the reaction with calcium sulfate and water and allows the formation of ettringite (Ca 6 Al 2 (SO 4 ) 3 (OH) 12 ·26H 2 O) and microcrystalline aluminum hydroxide Al(OH) 2 [ 45 ].…”

“…Ye’elimite contains about 50% wt. of Al 2 O 3 thus, the required alumina content in the raw materials to produce CSACs is above 20%, which can come from sources such as bauxite or industrial by-products, such as the ones proposed in the work by Canbek et al, namely red mud and sulfate-rich/high-lime fly ash [ 46 ]. However, the availability of low-cost sources of alumina-rich raw materials is certainly a limitation for the generalized use of CSACs [ 46 ].…”

Currently, the production of one ton of ordinary Portland cement (OPC) releases considerable amounts of CO2 into the atmosphere. As the need and demand for this material grows exponentially, it has become a challenge to increase its production at a time when climate-related problems represent a major global concern. The two main CO2 contributors in this process are fossil fuel combustion to heat the rotary kiln and the chemical reaction associated with the calcination process, in the production of the clinker, the main component of OPC. The current paper presents a critical review of the existent alternative clinker technologies (ACTs) that are under an investigation trial phase or under restricted use for niche applications and that lead to reduced emissions of CO2. Also, the possibility of transition of clinker production from traditional rotary kilns based on fuel combustion processes to electrification is discussed, since this may lead to the partial or even complete elimination of the CO2 combustion-related emissions, arising from the heating of the clinker kiln.
