“…Various researchers have utilized ash from MSW to understand the influence of various kinds of ash on different cementitious materials. Some researchers have looked into using various cementitious materials, including FA, to make Self-Compacting Concrete (SCC), and found that its physical and mechanical properties can meet the durability requirements [21]. Pawan Kumar et al [22] investigated the effects of recycled concrete aggregate and coal bottom ash on SCC properties.…”

“…Results showed that due to the presence of the calcite in the MSW-BA, the decline in the compressive strength was observed in the mixes. Taherlou et al [21] utilized the MSW-BA and treated industrial wastewater. Results showed that the MSW-BA, along with treated industrial wastewater, reduces the fresh properties of the SCC [21].…”

“…Taherlou et al [21] utilized the MSW-BA and treated industrial wastewater. Results showed that the MSW-BA, along with treated industrial wastewater, reduces the fresh properties of the SCC [21]. However, there are a few of the selected studies shown in Table 1 where the MSW-BA is used as coarse or fine aggregate, but there is no study as per the authors' knowledge that focuses on the utilization of MSW-BA with different grain size in high-performance concrete.…”

Globalization is bringing increased industrialization and municipal solid waste (MSW). This is a major concern in heavily populated areas. In order to reduce MSW generation, incineration is commonly used, resulting in two types of ashes: bottom and fly ash. Bottom ash is gathered at the incineration bed and is larger in mass than fly ash. To test the qualities of high-performance mortar, MSW-BA in three sizes (fine, medium, and coarse) was replaced with sand at three replacement levels of 10%, 20%, and 30%. The high-performance mortar integrating MSW-BA was tested for hardened density, mechanical properties such as compressive and flexural strength, resistance to NaOH solution, and heavy metal leaching. The substitution level of MSW-BA increased the hardened density of the mortar mixes. The volume change and residual strength of the mortar mixes were measured following exposure to the NaOH solution. Fine-particle mortar mixes shrank whereas medium- and coarse-particle mortar mixes expanded. The largest loss in flexural and compressive strength was recorded when 20% of sand was replaced with a fine fraction of MSW-BA. Heavy metals including cadmium and copper were not leached from MSW-BA combinations of any size. The minuscule amounts of lead and zinc discovered were well below acceptable limits. The present study illustrates the MSW-BA can be utilized as a substitute for sand in the development of high-performance mortar.

“…The primary goal of this article is to overcome this deficiency in the literature. Previously wastewater has only been used in the development of concretes [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ], and only olive oil mill wastewater has been tested for the development of clay brick [ 32 , 33 ]. However, mass production is not possible with such sources of water in the case of bricks.…”

Water is one of the necessary ingredients for construction materials. Billions of gallons of clean water are wasted during the development of fired clay bricks. Similarly, the waste of clean water is a global issue. In this study, we develop fired clay bricks with the help of wastewater for the first time and compare these with clay bricks produced using groundwater, which is the conventional method. Both destructive (i.e., compressive strength (CS)) and non-destructive (i.e., ultrasonic pulse velocity (UPV)) tests are conducted on all fired clay brick specimens as per the American Society for Testing and Materials (ASTM). Physical (i.e., dimensions) and durability (water absorption, efflorescence, etc.) tests are also conducted. All kinds of brick satisfied the standard requirements of physical and durability characteristics. Similar or better strength of bricks were achieved using wastewater. The study concludes that the testing results of wastewater bricks were significantly 15–25% higher compared with groundwater-fired clay bricks. A large amount of wastewater can be used to develop bricks, and clean water can be saved to attain circular economy goals. Therefore, this study will help not only in developing low-cost bricks but also in saving clean water.

“…This material exhibits not only excellent mechanical properties and acid–base resistance, fire resistance, and high-temperature resistance; but also significant advantages such as being low carbon, energy saving, and offering environmental protection by using industrial solid waste as the main raw material [ 7 ]. For example, Taherlou et al [ 8 ] studied the feasibility of simultaneously using different percentages of municipal solid waste incineration (MSWI) bottom ash (BA) and the treated industrial wastewater in self-compacting concrete. Ferone et al [ 9 ] studied three samples of municipal solid waste incineration fly ash (MSWI-FA) and stabilized them in systems containing coal fly ash to fabricate geopolymers through a polycondensation reaction.…”

A self-foaming alkali-activated lightweight material was prepared by the pretreatment of municipal solid waste incineration bottom ash (BA). The low weight could be achieved without adding a foaming agent by using the low-density and self-foaming expansion characteristics of BA in combination with a strong alkali. The effects of BA, liquid sodium silicate (LSS), and calcium hydroxide (CH) on dry and wet densities, as well as water absorption, are discussed. The results show that increasing the BA content can significantly improve the foaming effect and reduce the dry and wet densities of specimens. However, it also leads to a sudden decrease in compressive strength and a significant increase in water absorption. LSS and CH can significantly improve the ability to seal bubbles by accelerating condensation, and they further reduce dry and wet densities without significantly improving water absorption. It is most effective at BA, LSS, and CH contents of 60, 20, and 2%, respectively.
