A comprehensive analysis of the problems in sustainable construction and mitigation strategies

The challenges arising due to the construction industry in balancing the development along with ecological concerns are being focussed upon in this paper. The detailed analysis of the materials that are being brought to use as a sustainable material in the constructions sectors is being focussed upon. Since the late 20th century, there have been significant developments in the building industry. Since the population is rising and the need for housing is increasing, all available resources must be employed to satisfy the demand as it stands. This will have a significant long-term effect on the situation since the resources at hand are insufficient to meet the demand. There are many data and trends about sustainable construction approaches that is being developed by the researchers across the world that form the basis of this review study. The work found that associated industries should be encouraged to take part in the seminars, workshops, and other training programs that are organized at various events in order to deepen and improve their comprehension of the concept of sustainable development. The comparison drawn-out in between the conventional and a smart building concludes the benefits of using sustainable methods in the construction industry

Comparatively Study of Compressive Strength of Self-Compacting Concrete with Different Concrete Grade

In SCC, also called self-compacting concrete (SCC), voids are filled by its own weight, which prevents vibration. Large office building construction in Japan can significantly reduce noise levels on construction sites and associated environmental effects by implementing the use of SCC. According to the method, gravel makes up 50% of the concrete mix's packed density, while sand makes up 50% of mortar's packed density. Because gravel and sand are considered independently, SCC has a relatively high paste content. Thus, many SCC mixes are stronger than they should be. Recently, there has been a greater acceptance of the use of SCC. Concrete is a crucial and often utilised building material, hence attempts must be made to make it better by, for instance, constructing structures with enhanced mechanical and durability properties. The behaviour of concrete’s compressive strength and its splitting tensile strength is correlated. Analysis and experimental testing of self-compacting concrete (SCC) from different concrete classes were conducted. It was expected that both types of concrete would reach their desired compressive strengths of 25 N/mm2, 30 N/mm2, and 35 N/mm2 at 7, 14, and 28 days. Concrete sample measuring 150 mm in cube shape had their compressive and splitting tensile properties evaluated at 7, 14- and 28-days using compression testing apparatus

Regenerative Manufacturing: Crafting a Sustainable Future through Design and Production

In an era characterised by mounting environmental concerns and a growing awareness of the critical need for sustainability, the manufacturing industry stands at a crossroads. “Regenerative Manufacturing” emerges as a visionary strategy that not only tries to lower the ecological footprint of production but also seeks to restore and rejuvenate ecosystems, communities, and economies. This abstract provides a look into the profound potential of regenerative manufacturing, showcasing its main principles, processes, and its transformational impact on the future of design and production. Regenerative manufacturing signifies a fundamental transformation in the conceptualization, production, and use of items. The manufacturing process incorporates sustainability, circularity, and resilience throughout all its stages, encompassing material selection, design, production, distribution, and end-of-life concerns. The holistic approach discussed here places significant emphasis on the reduction of waste, optimisation of energy usage, and the utilisation of regenerative resources. This strategy aims to establish a regenerative cycle that actively supports the nourishment of the environment, rather than causing its depletion By employing novel methodologies such as biomimicry and generative design, this approach effectively harnesses the knowledge inherent in nature to stimulate the development of sustainable solutions. The regenerative manufacturing paradigm places significant emphasis on the core principles of collaboration and inclusivity. The recognition of the interconnection of all stakeholders is evident, encompassing producers, designers, customers, and local communities. By promoting openness and upholding ethical standards, this approach facilitates socially responsible production techniques that enhance the agency of local economies, safeguard cultural heritage, and prioritise the welfare of employees. The revolutionary capacity of regenerative manufacturing extends beyond the scope of specific goods and sectors. The power of this phenomenon lies in its ability to transform economic systems, facilitating a shift away from a linear model characterised by the processes of extraction, production, and disposal, towards a regenerative and circular economy. This transition offers not alone ecological advantages, but also financial robustness and enduring success

Comparative Study of Destructive Method and Non-destructive with Ultra-Sonic Pulse Velocity Method

The appropriate percentages of cement, fine aggregates, coarse aggregates, and water are utilized to make concrete. Due to its relatively low price and widespread availability, it is a ubiquitous building material. Concrete in its fresh state can also be molded into any desired shape and size. Strength and durability are two of concrete’s most important characteristics (particularly when used for structural purposes). Verify the concrete’s compressive strength before placing it under the expected loads. NDT methods, both destructive and non-destructive, can be used to assess the compressive strength of hardened concrete. A non- destructive test does not harm the concrete specimen, whereas a destructive test (DT) crushes the cast specimen until it breaks. In non-destructive testing, materials, components or assemblies are inspected, tested or evaluated without destroying their serviceability. This study compares the compressive strength of concrete utilising an ultrasonic pulse velocity approach, which is both destructive and non-destructive. Concrete cubes measuring 150 mm by 150 mm by 150 mm were created using the concrete mix grades 25N/mm2 and 30N/mm2, and they were allowed to cure for 28 days. There were 12 cubes produced and used for the study. The determine compressive strength between destructive and non -destructive (ultra-sonic pulse velocity) test method

Integration of UPFC in Solar PV Systems for Enhanced Green Energy Transmission

The recent world is being focused on deriving methods for using renewable energy-based systems to meet the energy demands. There are various research areas to be focused upon for making the output from these energy systems more reliable and efficient. The focus of this paper is on examining on such key component, a Unified power flow Controller (UPFC) into solar Photovoltaic (PV) structures to enhance green energy transmission and efficiency. The UPFC structure has the benefits combining the STATCOM and SSSC, which is found to be vital in regulating the active and reactive power flows within the network, ensuring stability amidst system fluctuations. The software MATLAB/SIMULINK is being used for making a 400.0-kW PV-UPFC farm, the study explores the effect of UPFC on enhancing power quality and stability, addressing real-world challenges like harmonics and voltage fluctuations like sags/swells. The work also delves into novel control strategies, consisting of using Proportional-integral (PI) controllers and advanced optimization techniques, to manage the power flow effectively. It can be concluded that the research highlights the UPFC’s capability in mitigating issues inherent in integrating solar energy into the grid, inclusive of voltage rise, reverse power flow, and system instability, by means of showcasing more desirable system voltage profiles and decreased energy oscillations in the designed system
