“…The results of the TSR test show that 25% of RCA has the maximum TSR, so it has the best moisture damage resistance as compared to other percents of RCA. It was examined by Udvardi et al [21], using aluminum dross as a possible filler for asphalt. According to the test results, these fillers can be used in asphalt mixes.…”

The management of building and demolition waste is an important subject in the government's sustainability efforts. Today, recycling and reusing industrial waste and by-products is a topic of considerable relevance in every industry, but it is especially important in cement and concrete technology. Within the asphalt pavement sector, the necessity for environmentally friendly highway design and construction is at the top of the priority list. Nevertheless, due to the inferior behavior of the resulting recycled concrete aggregate (RCA) mixes, additional enhancement materials are needed. In this study, the effect of using alumina waste in the form of secondary aluminum dross (SAD) in the asphalt compacted specimens that contained RCA as coarse aggregate was discussed. The conventional limestone dust filler is replaced by SAD at rates of 10, 20, and 30% by filler weight in the control mix, and then the best percentage is used in mixtures containing RCA at rates of 25, 50, 75, and 100%. The experimental work includes volumetric properties by employing the Marshall design method, indirect tensile strength (ITS), and compressive strength. All the used percent of SAD enhanced the properties of the asphalt mixture; the tensile strength ratio (TSR) of the control mixture increased by 4.58%, 8.52%, and 7.64% for SAD rates (10, 20, and 30%), respectively. The best dosage of SAD was added to the mixture containing RCA at different specified rates. The maximum TSR (13.92%) was obtained at 25% RCA. The same steps were followed in the compressive strength test; adding SAD increased the index of retained strength (IRS) of the control mixture by 55.11, 13.42, and 9.13% for 10, 20, and 30%, respectively. Thereafter, the best dosage of 20% SAD was added to the hot mix asphalt (HMA) containing different RCA percents. The maximum IRS (17.43%) was also obtained at a 25% RCA.

“…Strength can be increased by increasing cohesion between mineral and bituminous materials. In addition, the shape of the mineral material used in the asphalt mixture will affect the internal friction of the mineral framework and the carrying capacity of the asphalt pavement (Udvardi et al, 2019). Cold bituminous emulsion mixes (CBEM) are widely used as bitumen in India, which have low strength.…”

Aluminum black dross is produced by the secondary smelting process of aluminum. Aluminum black dross is classified as hazardous waste because it is reactive with water and produces substances and gases that are harmful to humans and the environment. Generally, aluminum black dross is managed by landfill method, but because it is produced in large amounts every year, the aluminum black dross needs to be utilized to reduce the impact on the environment. Aluminum black dross consists of large amounts of metal oxide and salts. The amount of metal oxide content in aluminum black dross can be used as raw material. This paper review types of processes for utilizing black dross aluminum as raw material in value-added products. aluminum black dross can be used as alumina, adsorbent, zeolite, composites, geopolymers, refractories, and fillers. By utilizing aluminum black dross waste into various products that have economic value, besides being able to protect the environment, it can also reduce environmental resource use.

“…Therefore, a good management method is needed for the tremendous increase in the volume of industrial waste. Aluminum dross had been utilized via several processes and can be classified into wet, dry, and without process [14][15][16][17][18][19][20][21][22][23][24]. The wet process was carried out using acid and base leaching for Al recovery [15], absorbent/catalyst [16,17], and alumina [18,19] productions.…”

“…The dry process was conducted by heating at a temperature above 1000 • C for the production of composite [20], refractory [21], and hercynite [22]. Aluminum dross can also utilize directly without processing for the production of geopolymers [23] and filler [24].…”

Mill scale and aluminum dross are the industrial wastes from steel and aluminum industries, which have high concentrations of Fe2O3 and Al2O3, respectively. This paper reports the conversion of reducible metal oxides in scale and dross into an alloy via carbothermic reduction at 1550 °C. Scale and dross were mixed with graphite into three different C/O molar ratios of 1, 1.5, and 2 to produce a pellet. The pellets were heated at 1550 °C for up to 6 h under an argon atmosphere. By this method, carbothermic reductions were found to proceed and formed Fe–Si–Al–C alloy that consists of Fe3Al and Fe3Si phases. The presence of Si in the alloy came from the reduction of SiO2 in aluminum dross. Levels of Al and Si in the alloy increase with increasing C/O molar ratios. However, the Si level in the alloy was found to stabilize since 3 h, while the Al level increases with increasing time up to 6 h. Unreacted oxides in the wastes had an insignificant effect on the ferroalloy formation. These results provide evidence for carbothermic reduction of the Fe2O3-Al2O3-SiO2 system at 1550 °C and show the novel method to upcycling aluminum dross and mill scale toward a circular economy.
