“…In addition, these authors obtained compressive strength and flexural strength values of 24.79 and 4.895 (N/mm 2 ), respectively [72]. However, in another study performed by the same researchers, the best ratio for hybrid tile composed of waste plastic, rice husk ash, and sand was 1:1:2 [73].…”

On a global scale, millions of tons of diverse agricultural residues are generated annually. Most of these wastes are burned or dumped in landfills, which causes environmental pollution. Addressing environmental issues arising from agricultural waste materials, in addition to mitigating heating and cooling expenses in the construction sector, is an interesting challenge for researchers. The utilization of agricultural wastes in different parts of construction is producing positive findings day by day, and investigating research in this field is a curiosity for researchers. This short study reviewed the most recent achievements in using agricultural wastes as a substitute or additive material for construction. Using these wastes as aggregate, ash (as a supplementary for cement), or fibers for foam concrete, insulation materials, etc. has been reviewed. This review has focused on very recent published papers. Several studies have demonstrated the effective influences of agro-waste materials in construction, like retaining the compressive strength (155 MPa) of concrete at standard levels and reducing heat losses in buildings (69% energy savings for brick insulated using wheat straw), as well as sound insulation. The use of agro-waste materials for insulation positively improved thermal conductivity, costs, and energy savings. However, some wastes did not provide a high added value, which shows that more investigations still need be performed to fill this gap in the research. Considering the global scale of agricultural waste generation and the potential benefits to both the environment and construction industry, continued research in this area is essential.

“…The correctness of the developed HYBD_MCDM is examined through three tiers. The first tier involves adopting Spearman's rank correlation analysis to measure the similarities between the generated rankings from the investigated MCDM models [124][125][126]. In the second tier, the obtained rankings from the developed HYBD_MCDM model are compared against CoCoSo, WISP, MARCOS, CODAS, WASPAS, TOPSIS, FANP and weighted product model (WPM).…”

Public–private partnership (PPP) infrastructure projects have attracted attention over the past few years. In this regard, the selection of private partners is an integral decision to ensure its success. The selection process needs to identify, scrutinize, and pre-qualify potential private partners that sustain the greatest potential in delivering the designated public–private partnership projects. To this end, this research paper proposes an integrated multi-criteria decision-making (MCDM) model for the purpose of selection of the best private partners in PPP projects. The developed model (HYBD_MCDM) is conceptualized based on two tiers of multi-criteria decision making. In the first tier, the fuzzy analytical network process (FANP) is exploited to scrutinize the relative importance of the priorities of the selection criteria of private partners. In this respect, the PPP selection criteria are categorized as safety, environmental, technical, financial, political policy, and managerial. In the second tier, a set of seven multi-criteria decision-making (MCDM) algorithms is leveraged to determine the best private partners to deliver PPP projects. These algorithms comprise the combined compromise solution (CoCoSo), simple weighted sum product (WISP), measurement alternatives and ranking according to compromise solution (MARCOS), combinative distance-based assessment (CODAS), weighted aggregate sum product assessment (WASPAS), technique for order of preference by similarity to ideal solution (TOPSIS), and FANP. Thereafter, the Copeland algorithm is deployed to amalgamate the obtained rankings from the seven MCDM algorithms. Four real-world case studies are analyzed to test the implementation and applicability of the developed integrated model. The results indicate that varying levels of importance were exhibited among the managerial, political, and safety and environmental criteria based on the nature of the infrastructure projects. Additionally, the financial and technical criteria were appended as the most important criteria across the different infrastructure projects. It can be argued that the developed model can guide executives of governments to appraise their partner’s ability to achieve their strategic objectives. It also sheds light on prospective private partners’ strengths, weaknesses, and capacities in an attempt to neutralize threats and exploit opportunities offered by today’s construction business market.

“…MCDM facilitates the consideration of trade-offs between environmental impacts, economic costs, social benefits, and durability parameters, enabling a more balanced decision-making approach. Previous investigations have shown that MCDM methods can be successfully used in concrete materials [40][41][42][43][44][45][46]. For instance, Kurda et al [40] utilized a novel MCDM method to assess the overall sustainability of cementitious materials, validating this approach to analyze non-traditional materials in terms of mechanical properties, cost, environmental impact, and service life.…”

In previous literature, multi-criteria decision-making (MCDM) methods and life cycle assessment (LCA) methods, integrating different properties, have been applied to cementitious materials separately. This study addresses the existing gap in the research by comparing LCA methods with durability parameters integrated and MCDM methods in concrete mixtures. The aim is to assess the differences between these two approaches when assessing the overall sustainability of cementitious materials. Concrete mixtures containing conventional and recycled materials, such as supplementary cementitious materials (SCMs) and recycled concrete aggregate (RCA), are evaluated based on their mechanical properties, durability parameters, environmental impact, and cost. The results highlight the positive impact of SCM usage on concrete performance and emphasizes the importance of reducing cement content for sustainability. Careful RCA utilization is crucial due to the variable outcomes when combined with SCMs. The results also exhibit that various MCDM methods show acceptable differences when ranking concrete mixtures, offering flexibility in property weighting for concrete applications. In contrast, different LCA methods with durability integrated yield higher differences, emphasizing the superior consistency of MCDM methods. The sensitivity analysis highlights the significance of weight methods and concrete parameters. Standardizing procedures for specific concrete applications is recommended to ensure the reliability and relevance of results.
