“…The use of aggregates obtained through the comminution of CDWs for reuse in construction constitutes an alternative that must be considered due to their long-term environmental impact (Guzmán et al, 2017;Ulloa-Mayorga et al, 2018;Gaggino, 2019;Restrepo-Zapata and Cadavid-Restrepo, 2019;Ceballos-Medina et al, 2021;Amarilla et al, 2021;Abera, 2022) for this, awareness, commitment and effective management are important (Kabirifar et al, 2020;Yu et al, 2021). These environmentally friendly, energy-efficient, and cost-effective alternative materials produced from solid waste will show good market potential in different contexts (Ahmad et al, 2017;Abid et al, 2022;Garzón et al, 2022) that enables the application of digital technologies such as modeled building information in CDW waste management (Yuan, 2017;Waskow et al, 2020;Mymrin et al, 2021;Shi and Xu, 2021;Abina et al, 2022;Oluleye et al, 2022;Tan et al, 2022;Wu et al, 2022) and the adoption of the circular economy in the construction industry (Ruiz et al, 2020;Umar et al, 2021;Christensen, 2022;Oluleye et al, 2022;Shooshtarian et al, 2022;Wu et al, 2022;Yu et al, 2022;Zhang et al, 2022).…”

“…In pursuit of sustainable construction practices, researchers have been investigating the use of alternative raw materials, particularly in the development of eco-friendly concrete (Guzmán et al, 2017;Kumar et al, 2020;Suchithra et al, 2022). Consequently, there have been multiple research proposals exploring the potential of utilizing waste materials for the production of ecological bricks (Guzmán et al, 2017;Ceballos-Medina et al, 2021).…”

The aim of this study is to examine the association between organizational justice and organizational citizenship behavior (OCB) among female workers in Saudi Arabia. Organizational justice has been acknowledged as a significant predictor of employee attitudes and behavior; however, its impact on the OCB of female workers in Saudi Arabia remains underexplored. To address this research gap, a cross-sectional survey was conducted among female workers in various organizations in Saudi Arabia. The study assessed organizational justice by considering three dimensions: distributive fairness, procedural fairness, and interactional fairness. Additionally, OCB was measured using a scale adapted from previous research. The collected data were subjected to regression analysis. The study findings indicate a positive relationship between organizational justice and OCB among female workers in Saudi Arabia. Specifically, distributive fairness, procedural fairness, and interactional fairness exerted a significant positive influence on OCB. This research contributes to the existing literature by providing empirical evidence on the impact of organizational justice on OCB among female workers in Saudi Arabia. Furthermore, it extends prior research by investigating the specific dimensions of organizational justice that affect OCB. Nonetheless, there are certain limitations to this study. Firstly, its cross-sectional nature restricts the ability to draw causal inferences. Moreover, the absence of comparisons with other cultural and national contexts represents another limitation. In conclusion, this study holds important implications for organizations in Saudi Arabia and elsewhere that aim to foster OCB among female workers. The findings suggest that enhancing organizational justice can lead to positive work behaviors among female employees. Future research should explore the generalizability of these findings to other contexts and investigate the potential moderating effects of cultural factors.

“…For a wide production and application of Partition Blocks manufactured from waste materials, more research and development are needed, not only in the technical, economic and environmental areas, but also in standardization, government policy and public education related to recycling, waste and sustainable development [ 2 , 8 , 16 , 17 , 18 , 19 , 30 , 31 , 32 , 33 , 34 ].…”

“…There are no limits to the use of aggregates obtained by crushing rubble (mortars, bricks and concrete), since they constitute another alternative material to paving stones or facade cladding, favoring applications such as pedestrian paths in gardens for architectural landscaping and the improvement of the urban image [ 16 ]. With a view to implementing the above, Xue-Fei et al 2021 [ 17 ] conducted experimental research on the mechanical strength and durability of chopped basalt fiber-reinforced recycled aggregate concrete.…”

Recovery of Mixtures of Construction Waste, PET and Sugarcane Bagasse for the Manufacture of Partition Blocks

et al. 2022

View full text Add to dashboard Cite

The building industry generates millions of tons of construction and demolition waste annually (12 million tons/year are generated in Mexico, of which only 4% is reused or recycled). Concomitantly, the demand for goods and services by the building industry causes significant environmental impacts. On the other hand, plastic waste is also difficult to assimilate into the environment in the short term, and its recovery is of special interest. Therefore, this research focuses on the feasibility of the manufacture of Partition Blocks (essential building element) through the combination of construction and demolition waste (CDW), polyethylene terephthalate (PET) plastic flakes, dust from tire shredding, and residue from the sugar industry (bagasse). The results of this study show that the Partition Blocks made with CDW and PET reach an average compressive strength of 115.003 kgf/cm2 (11.278 MPa) (suitable for structural use according to Mexican regulations); the use of lime enhances the consistency of the mixture of CDW and PET (increases its cohesion and homogeneity); and finally, these Partition Blocks have a cost comparable to the current conventional Partition Blocks made with virgin material, thus, conferring them validity as a feasible recycling option for these residues.

“…A nivel global, la magnitud del problema de los RCD es evidente, con una alarmante producción anual de aproximadamente 461 millones de toneladas (Ceballos & Gonzales, 2021). Este dato revela que un 10% de los materiales empleados en la construcción terminan convertidos en residuos, una proporción que se incrementa hasta diez veces más en el caso de las operaciones de demolición.…”

La perspectiva de tratar y reciclar los residuos de construcción y demolición (RCD) como componentes en la fabricación de hormigón y mortero ha emergido como un tema de suma importancia en la industria de la construcción. La presente investigación tiene como objetivo analizar, a través del estudio comparativo las propiedades mecánicas y físicas del mortero y hormigón elaborado con áridos naturales y reciclados. La metodología aplicada en esta investigación tiene un enfoque cuantitativo basado en un estudio experimental, del cual se llevó a cabo realizando una serie de pruebas basadas en las normas NTE-INEN y ASTM. En la dosificación del motero y hormigón se aplicó una relación agua/cemento constante de 0.4. Los porcentajes de sustitución de árido natural por reciclado fueron del 0%, 15%, 20% y 25%. Las series de los especímenes del mortero y hormigón fueron sometidas a un tiempo de curado de 7, 14 y 28 días respectivamente. Los resultados obtenidos mostraron que la aplicación de un 15% de árido fino reciclado en el mortero proporciona una resistencia a la compresión comparable con la muestra de control. En el caso del hormigón, se determinó que la inclusión de un 15% de árido grueso reciclado produce resultados similares en resistencia a compresión y resistividad eléctrica con la muestra de control. Este estudio proporciona evidencia sólida que respalda la viabilidad técnica y las ventajas de utilizar áridos reciclados en la fabricación de hormigón y mortero, lo que contribuye significativamente a la sostenibilidad de la industria de la construcción.
