“…This strategy poses a high positive influence on human health, promoting the social acceptance of crop waste recycling in the industrial sector [2]. Employing multi-criteria decision-making (MCDM) tools could assist decision-makers in considering the sustainability, affordability, reliability, and functionality of cement-manufacturing systems [19]. Cement-manufacturing companies are often operated in a complex and uncertain environment, because different stakeholders and owners have various priorities and perceptions [20].…”

This study focuses on recycling Shammi corn stalks in the cement industries, further avoiding air and soil pollution caused by their improper disposal. This crop residue was thermally treated at 700 °C for 2 h under an oxygen-rich environment to produce Shammi corn stalk ash (SCSA). This SCSA was used as a cement replacement material (2–10%, w/w), whereas the control sample included only cement. The compressive strength values for the 4% (w/w) replacement ratio at 2-, 7-, and 28-day ages were greater than those for the control by 26.5%, 15.8%, and 11.4%, respectively. This 4% (w/w) also maintained a better flexural strength than other mixtures, with proper initial and final setting times (135 and 190 min), workability (18.5 cm), and water consistency (27.5%). These mechanical/physical properties were integrated with socio-enviro-economic data collected from experts through a pairwise comparison questionnaire, forming the inputs of a multi-criteria decision-making (MCDM) model. Recycling SCSA in the cement-manufacturing process attained positive scores in the achievement of the three pillars of sustainable development, revealing an overall score greater than the control. Hence, the study outcomes could be essential in developing green concrete, cement blocks, and mortar, based on the sustainable development goals (SDGs) agenda.

“…The method was first introduced by George Derringer & Ronald Suich in 1980 [76]. Though there are many other advanced methods that have been developed for multi objective optimization [77,78], the desirability function method has been widely used in existing studies [79][80][81][82] and hence the same methodology has been adopted in the present study.…”

Energy from coal-fed thermal power plants is provided at the cost of the generation of coal ash. Coal bottom ash (CBA) is an ash generated in coal-fed power plants which is landfilled. Existing literature reports the potential of CBA as a replacement for Portland cement (PC) and natural fine aggregates (NFA) in concrete. Carbonation is an important durability parameter of concrete having fatal consequences at later ages if not estimated and controlled as it leads to corrosion in reinforcement. In the present study, experimental, microstructural, and statistical analysis along with life cycle assessment was performed to investigate the combined effect of two-hour grinded CBA (GCBA) as PC (10-30%) and raw CBA as NFA replacement (0-50%) on compressive strength and carbonation resistance. Accelerated carbonation tests were performed at an exposure of four weeks after 28 and 90 days of curing. Among CBA-based concrete mixes, concrete with 20% GCBA and 25% CBA (G20C25) reported higher compressive strength and carbonation depth owing to pozzolanic reactivity and filler effect of fine CBA particles. However, G20C25 resulted in comparable performance in comparison with the control mix in terms of strength and carbonation resistance. The findings of X-ray diffraction spectroscopy, scanning electron microscopy and Fourier transform infrared spectroscopy also validate the trends. The mathematical models derived for the carbonation resistance and strength were well-fitted. Multi-objective optimization recommended 21.5% GCBA and 29.8% CBA as the optimum amount that resulted in 20.08% and 19.40% lower carbon footprints and eco-costs compared to control mix.
