“…Since the last decade, the application of supplementary cementitious materials (SCMs) such as silica fume, fly ash (FA), slags, etc., as a cement replacement has been emphasized [ 24 , 25 , 26 ]. SCMs hydrate cement hydraulically or pozzolanically in pore solution [ 27 , 28 , 29 ]. Thus, utilizing industrial solid waste in construction as SCMs is an effective approach for eco-friendly construction [ 30 ]; it could reduce cement demand, reduce CO 2 emission, and solve waste management problems.…”

This study aimed to expand the knowledge on the application of the most common industrial byproduct, i.e., fly ash, as a supplementary cementitious material. The characteristics of cement-based composites containing fly ash as supplementary cementitious material were discussed. This research evaluated the mechanical, durability, and microstructural properties of FA-based concrete. Additionally, the various factors affecting the aforementioned properties are discussed, as well as the limitations associated with the use of FA in concrete. The addition of fly ash as supplementary cementitious material has a favorable impact on the material characteristics along with the environmental benefits; however, there is an optimum level of its inclusion (up to 20%) beyond which FA has a deleterious influence on the composite’s performance. The evaluation of the literature identified potential solutions to the constraints and directed future research toward the application of FA in higher amounts. The delayed early strength development is one of the key downsides of FA use in cementitious composites. This can be overcome by chemical activation (alkali/sulphate) and the addition of nanomaterials, allowing for high-volume use of FA. By utilizing FA as an SCM, sustainable development may promote by lowering CO2 emissions, conserving natural resources, managing waste effectively, reducing environmental pollution, and low hydration heat.

“…Desse modo, atualmente, existem diversos estudos que visam meios para a mitigação desses impactos, além da redução de custos da produção do cimento. Estas investigações propõem desde a reutilização de rejeitos, uso de matérias-primas naturais e Materiais Cimentícios Suplementares (Gupta & Chaudhary, 2022;Laidani et al, 2020).…”

As bentonitas são materiais argilosos compostos principalmente por montmorilonita (mineral do grupo das esmectitas). A sua composição coloidal característica determina a incorporação de água, formando pastas plásticas. Sejam sódicas ou cálcicas, as bentonitas são amplamente utilizadas em inúmeras aplicações industriais devido as suas características estruturais, disponibilidade e abundância na natureza, e baixo custo. O presente trabalho teve como objetivo realizar uma breve revisão narrativa da literatura sobre a potencialidade das argilas bentoníticas quanto às suas características e algumas aplicações. Foram selecionados artigos entre os anos de 2017 a 2022 a partir da plataforma Science Direct e utilizando as seguintes palavras-chave: Bentonite, environmental remediation, cosmetics and pharmaceuticals, biomedicine, and civil construction. Os resultados evidenciaram que a área de aplicação mais estudada foi a de remediação ambiental conectada às investigações em adsorção, o que demonstra o alto interesse e motivação dos pesquisadores por temas relacionados à sustentabilidade. Portanto, espera-se que esta leitura preliminar possa contribuir para a compreensão do potencial tecnológico da bentonita, trazendo claridade ao estudo de suas propriedades e aplicações.

“…Again, as revealed by Tingley et al (2017), the general lack of demand for composite construction in itself prevents building owners from venturing into construction material options that allow for the use of reclaimed materials. This barrier is further affected by the low market value of recovered or reclaimed materials , borne from the perception of inferiority of such materials (Gupta and Chaudhary, 2020;Kledy nski et al, 2020) and the high costs of these reclaimed materials. Furthermore, the profitfocused nature of the construction industry (Grafstrom and Aasma, 2021) dissuades the recycling of demolishing waste when the costs of dumping at landfills are substantially lower.…”

“…Under this category, limited design codes focusing on reclaimed materials, lack of building design standards for reducing CDW and lack of policy incentives (Veleva et al, 2017;Ghisellini et al, 2018;Gupta and Chaudhary, 2020;Kledynski et al, 2020;Rakhshan et al, 2021) were seen as the highest-occurring barriers. Some studies have shown that there is scanty information as to how buildings can be designed using reclaimed materials Charef and Emmitt, 2021).…”

“…the 3R approach (Reduced, Reused and Recycle) Mahpour, 2018). Many of the technological barriers identified in the literature are related to the lack of appropriate tools, technology and procedures to recover or reuse materials (Gupta and Chaudhary, 2020;Pitti et al, 2020). The immature recycling technology available has been cited to prevent construction managers from having to recycle their materials (Kifokeris and Xenidis, 2017).…”

PurposeThis study aimed to identify barriers impeding circular economy (CE) uptake in the construction industry in literature, categorize them for the development of a framework and to seek the interrelationships among the categorized barriers. This allowed for identifying integrated solutions to holistically address the barriers. The study also sought to identify the “hot” themes, the knowledge gaps and future research directions on barriers impeding CE.Design/methodology/approachForty-eight relevant articles were desk reviewed from different construction peer-reviewed journals and published conference papers. A scientometric analysis allowed for co-occurrence of keywords relating to CE. A content analysis enabled the identification of 79 barriers impeding the uptake of CE in the construction industry which were further categorized into six distinct categories for the development of a framework showing the interrelationships among the categorized barriers.FindingsThe identified barriers include construction sector inertia, lack of design standards, lack of knowledge, awareness and understanding, design cost, and perception of second-hand materials as substandard among others. The study categorized the identified barriers for better understanding into six different groups: cultural barriers, social barriers, environmental barriers, economic barriers, technical barriers and technological barriers. Strategies to address the barriers were also proposed. The interrelationships among the various barriers were also shown in a proposed framework to educate professionals on the interconnectivity of the barriers.Practical implicationsCategorization of the various barriers impeding CE uptake contributes to the body of knowledge. Also, the interrelationships among the various categorized barriers in the framework will enable construction professionals make informed decisions regarding the successful integration of CE in the industry, better appreciate the barriers that impede CE uptake and apply strategies to holistically address the barriers. This will expand current knowledge outside the narrow scope of isolated barriers.Social implicationsTo the global construction industry, the review presents a list of barriers and their interrelationships that could provide implementation strategies for the uptake of CE in the industry.Originality/valueThe geographical scope of this study is not limited, and therefore encourages wide applicability of the findings to the global construction industry.
