“…Regarding sustainability, safety principles have emphasized a variety of hypotheses and explanations. Regarding their contact with PD, they may be divided into two groups: dependent and autonomous characteristics [29,30]. There are additional qualitative aspects of independent safety and sustainability that may be measured via various dimensions, and PD may offer such characteristics of the environment, such as energy performance and lightning [31].…”

To maximize profits without sacrificing quality, the concept of sustainable construction must be adopted across a project’s whole lifespan. Although adopting the idea of passive design in developing countries is incomplete, these studies have focused on the reasons for doing so. In contrast, there is limited evidence to completely analyze the influence of integrating passive design on the project sustainable success (PSS) of projects throughout their existence. This study focuses on the hurdles to passive design adoption in Pakistani building projects. It evaluates the impact of overcoming passive design (PD) adoption barriers on project sustainability success (PSS) during the duration of the project. Therefore, a more comprehensive literature assessment is required for conceptual model construction. Using a survey assessment instrument, Structural Equation Modeling (SEM) was constructed (i.e., a questionnaire). A total of 156 construction experts in Pakistan provided information. The result of the model demonstrated that the elimination of PD implementation obstacles had a moderate to high impact on PSS throughout the building structure’s lifetime. These results provide the foundation for legislation in a number of Asian nations about the efficient completion of projects via the removal of obstacles for the use of passive design. Similarly, the adoption of passive design will increase the success of the construction project.

Concrete is a widely utilized construction material globally; however, it is characterized by a fundamental deficiency in its tensile strength when it is not reinforced. The incorporation of diverse novel materials into concrete is being pursued with the aim of mitigating its limitations while concurrently enhancing its reliability and sustainability. Furthermore, it is noteworthy that concrete embodies a significant quantity of carbon. The primary cause of this phenomenon can be attributed to the utilization of cement as the principal binding component in concrete. Recent advancements in research have indicated that jute fiber, commonly referred to as JF, exhibits considerable potential as a novel material for enhancing the mechanical robustness of concrete. Although there is a significant body of literature on the application of jute fiber in concrete, there has been a dearth of research on the capacity of jute fiber (JF) to improve the mechanical strength of concrete and mitigate its carbon emissions. This study aims to cover a gap in the existing literature by analyzing and enhancing the application of JF in relation to its mechanical properties and environmental impact. The study involved conducting experiments wherein JF was added at varying weight percentages, specifically at 0%, 0.10%, 0.25%, 0.50%, and 0.75%. The investigation encompassed a number of examinations of both the fresh and hardened states of concrete, in addition to assessments of its durability. The fresh concrete tests included the slump test, while the hardened concrete tests involved measuring compressive strength (CS), split tensile strength (STS), and flexural strength (FS). Additionally, the durability tests focused on water absorption (WA). The study involved the computation of embodied carbon (EC) ratios for various mix combinations. The findings suggest that incorporating JF into concrete results in a decrease in environmental impact relative to alternative fiber types, as demonstrated by a rise in eco-strength efficiency (ESE). Based on the findings of the conducted tests, an optimal proportion of 0.10% JF has been determined to be conducive to enhancing the CS, STS, and FS by 6.77%, 6.91%, and 9.63%, respectively. The aforementioned deduction can be inferred from the results of the examinations. Using data obtained from extensive experimentation, the RSM (Response Surface Methodology) was used to construct a model. The model was optimized, resulting in the establishment of definitive equations that can be used to evaluate the effects of incorporating JF into concrete. Potential benefits have been identified for the advancement of concrete in the future through the utilization of JF.

“…These include PVA (Polyvinyl alcohol) fibre, fibre of carbon, jute fibre, steel fibre, nylon fibre, basalt fibre, coir fibre, and glass fibre [9]. Previous studies have indicated that incorporating various materials, such as fibre-reinforced polymer, into the concrete mixture can enhance the strength of the concrete [10][11][12]. The incorporation of fibres into the cementitious matrix results in the suppression of crack propagation within the material.…”

Concrete is a worldwide construction material, but it has inherent faults, such as a low tensile strength, when not reinforced with steel or other forms of reinforcement. Various innovative materials are being incorporated into concrete to minimise its drawbacks while concurrently improving its dependability and sustainability. This study addresses the research gap by exploring and enhancing the utilisation of glass fibre (GF) concerning its mechanical properties and reduction of embodied carbon. The most significant advantage of incorporating GF into concrete is its capacity to reduce the obstruction ratio, forming clusters, and subsequent material solidification. The study involved experiments wherein GF was incorporated into concrete in varying proportions of 0%, 0.5%, 0.75%, 1%, 1.25%, 1.50%, 1.75%, and 2% by weight. Mechanical tests and tests for durability were conducted, and Embodied carbon (EC) with eco-strength efficiency was also evaluated to assess the material’s sustainability. The investigation found that the optimal percentage of GF to be used in concrete is 1.25% by weight, which gives the optimum results for concrete’s mechanical strength and UPV. Adding 1.25% GF to the material results in increases of 11.76%, 17.63%, 17.73%, 5.72%, and 62.5% in C.S, STS, F.S, MoE, and impact energy, respectively. Concrete blended with 1.25% of GF has the optimum value of UPV. The carbon footprint associated with concrete positively correlates with the proportion of GF in its composition. The optimisation of GF in concrete is carried out by utilising the response surface methodology (RSM); equations generated through RSM enable the computation of the effects of incorporating GF in concrete.
