“…The findings showed that bricks with the highest maximum strength had an FA to RM ratio of 60:40 independent of the firing temperature. Furthermore, the results also showed that increasing the firing temperature enhanced the strength of the bricks, whereas the use of sawdust blending enhanced the porosity and thermal insulation of the bricks [32]. Bricks that were made by blending sawdust (7.5%) and 40% red mud at 1100 • C were able to meet the criterion of Type A insulation bricks specified by IS:2042.…”

“…The findings showed that a maximum of 10% wood chip content generated bricks with the highest compressive strength and water absorption rates, while the thermal conductivity was reduced by up to 50%. A comparison of Muñoz et al [33] against Mandal, Verma, and Sinha [32], who also used non-food related agro-wastes in making bricks, reveals a similarity in that only a minimal percentage of the waste products led to the high-quality bricks with optimal compressive strength and water absorption rates. Thermal features were also enhanced in both instances.…”

“…Other researchers have considered the use of other agro-wastes (not necessarily food wastes) such as sawdust as an additive agro-waste product from timber-related activities in brick production. For instance, Mandal, Verma, and Sinha [32] blended different concentrations of fly ash (FA) and red mud (RM) with sawdust in the preparation of insulation bricks. An examination of the effects of the FA to RM ratios, firing temperatures, and sawdust blending on the physical characteristics of the bricks were also conducted.…”

The construction sector, in modern times, is faced by a myriad of challenges primarily due to the increase in the urban population and dwindling natural resources that facilitate the production of construction materials. Furthermore, higher awareness on climate change is forcing companies to rethink their strategies in developing more sustainable construction materials. Diverse types of agro-waste ranging from rice husk ash (RHA), sugarcane bagasse ash (SCBA), and bamboo leaves ash (BLA) among others have been identified as potent solutions in the development of sustainable construction materials. In this review paper, six different construction materials, made using agro-waste products, are examined. The materials include brick/masonry elements, green concrete, insulation materials for buildings, reinforcement materials for buildings, particleboards, and bio-based plastics. The main criterion adopted in selecting the materials regards their popularity and wide-scale use in modern construction applications. Additionally, as this research emphasizes identifying alternative approaches to develop sustainable construction materials, the focus is directed toward mainstream materials whose continued use has an adverse impact on the environment. The findings obtained from the review showed that the use of agro-waste to develop sustainable construction materials was effective, as the developed materials adhered to established building standards. Therefore, this indicates that agro-waste materials have the potential to replace conventional construction materials and hence achieve economic, environmental, and social sustainability in the long run.

“…Many studies have reported the use of solid waste in the technology for making building materials. Solid waste can come from the flotation waste of coal enrichment [7], paper processing waste [8], sawdust, ash, the wastes from cellulose-paper and sugar production [9], from clay-containing arrays, granulated fine-ground crushed concrete and granulated blast furnace slag [10,11], the waste from aluminum plants: red sludge and fly ash [12], glass waste [13], etc. The relevance of such studies is predetermined by the need to expand the range of sorption materials (including local clay minerals) for water purification implying the subsequent disposal of waste and the possibility of their utilization as secondary resources.…”

Based on the modern ideas about environmental protection, this paper reports a study into the utilization of water-treated waste from heavy metals (using copper(II) compounds as an example) for the manufacture of ceramic building materials. The examined clay minerals from local deposits and the optimal conditions for their heat treatment (at 1,100 °C) have been proposed for the sorption removal of pollutants of inorganic origin from wastewater. The use of wastewater after its treatment makes it possible to address several tasks at the same time: to protect the environment from pollution by technological wastewater, as well as to reuse wastewater in order to resolve the issue of water scarcity. Ceramic building materials were manufactured based on water purification waste (in the amount of 5 %) and clay raw materials. Their structural-mechanical and physicochemical characteristics have been comprehensively studied. Sintering processes begin at lower temperatures, which is why, with an increase in the annealing temperature to 1,000 °C and higher, their strength rapidly decreases. In the temperature range of 600‒1,100 °C, there are possibilities to apply ceramic technology to immobilize heavy metals in ceramic matrices. The prospect of utilizing water purification waste in the technological process of manufacturing inorganic ceramic materials has been shown. The safety of the building materials, manufactured by leaching pollutants from the ceramic samples using various aggressive environments (leaching to 6.4 %, 0.083 mg·cm2/day) has been investigated. The high strength and degree of the copper ion fixation in the structure of polymineral clay have been confirmed while secondary environmental pollution is almost absent

“…The characterization and incorporation of waste from the aluminum industry as raw material in the manufacture of construction materials has been studied by different authors. Huang et al [18] characterized the mineral phases, metal content, and metal leachability of different salt cake from secondary aluminum production collected from different facilities across the U.S. Kumar Mandal et al [19] investigated the possible use of aluminum plant waste for the preparation of insulating bricks. The bricks were manufactured by mixing fly ash and red mud in different proportions with sawdust, studying the influence of the firing temperature.…”

Manufacture of Sustainable Clay Bricks Using Waste from Secondary Aluminum Recycling as Raw Material

The aluminum recycling industry produces aluminum filter dust (AFD), a waste byproduct of the aluminum recycling process composed mainly of aluminum oxide in a percentage between 60–70%, 8% calcium oxide, almost 15% sodium chloride, and between 5–10% potassium chloride. Due to its aluminum content, this waste can be used as a raw material in the manufacture of ceramic bricks, at the same time reducing the environmental impact produced in landfill. In this work, the partial substitution of a clay mixture (40% black, 30% red, and 30% yellow clay) by different proportions of AFD in the range 0–25 wt % for the production of fired clay brick was studied. The raw materials, clays, and waste were characterized by XRF and XRD. The brick specimens were fired at 950 °C and their physical and mechanical properties, such as water absorption, water suction, loss of ignition, linear shrinkage, bulk density, and compressive strength, were analyzed. The more relevant results were obtained with the addition of up to 20 wt % AFD, obtaining bricks with physical properties comparable to pure clay-based bricks used as a reference and better compressive strength and thermal conductivity due to the balance between the melting and pore-forming effects of the waste. These sustainable bricks also comply with the regulations of heavy metals leached to the environment, as indicated by the leaching test.
