    Abstract: This study compares the ecological footprints of geopolymer and red clay brick prisms, two common building materials for long-lasting masonry structures. The study’s goal is to shed light on the environmental performance of different brick kinds by a thorough review of sustainability indices such as embodied energy, CO2 emissions, water use, and trash creation. The results suggest that geopolymer bricks have better environmental features than red clay bricks, such as lower embodied energy, decreased CO2 emissions, lower water consumption, and less waste creation. These findings underline the promise of geopolymer bricks as an eco-friendlier masonry alternative that may improve green building performance. The report, however, stresses the need to think about more than only environmental damage. The sustainability and feasibility of utilising geopolymer and red clay bricks depend heavily on factors including durability, thermal performance, and cost-effectiveness. In order to make educated selections about brick selection, it is important to evaluate these variables. The results of this study provide the groundwork for more research on sustainable masonry materials and contribute to the development of environmentally aware building practises. Architectural and engineering professionals may encourage environmentally responsible building practises and help create a more sustainable and resilient built environment by taking this study’s findings into account.

    Abstract: In the current paper, AA6101-T6 aluminium alloy was subjected to friction stir welding (FSW) utilizing a vertical milling machine. Alloy plates were welded in butt position to provide a virtually flat interface, using a tool shape that was carefully selected. Because of the excessive generation of heat via the tool and workpieces during friction stir welding, substantial deformation in the nugget zone is seen. The mechanical attributes of the base metal at the joint are significantly impacted by an excessive variation in temperature at the weld. In this experiment, mechanical properties-related changes through the FSW process are kept to a minimum to achieve high tensile strength. The tool’s rotating speed (measured in rpm), the workpieces' traverse speed (measured in mm/min), and the tool tilt angle were chosen as the parameters to regulate the weld quality. As a result of its 44% contribution, the rotating speed parameter is shown to be the most beneficial one for stir welding. The metric determining transverse speed contributes the least, at 19%. For effective stir welding, such as high strength welds, defect-free welds, short welding times, low welding costs, etc., it is preferred that the tool rotational speed parameter be concentrated. By using sustainable Taguchi approach to optimize the chosen process parameter, high tensile strength is achieved at the welded connection.

    Abstract: This article investigates the merging of geopolymerization and plastic waste usage, imagining high-performance brick production that couples innovation with sustainability, in an effort to transform the environmental effect of the building sector. This idea is supported by the circular economy, which diverts resources from waste streams into a closed-loop paradigm. By creating inorganic polymers from aluminosilicate-rich sources, the chemical process of geopolymerization provides a paradigm change in the production of materials. This procedure is improved even more by the addition of plastic trash, which combats plastic pollution and improves brick qualities. In order to create a more resilient and environmentally conscientious construction industry in the future, this paper outlines the process’s complexities, advantages, and difficulties while arguing for a harmonic fusion of circular economy concepts, technical innovation, and environmental stewardship.

    Abstract: To achieve enhanced flux dissipation, microchannels heat sink are being effectively implemented in various engineering processes. Here, a numerical analysis is to be carried out on an open stepped micro pin fin heat sink (MPFHS) with different step size. The stepped pin fin heat sink (PFHS) having varied fin height in an array of two fins having inline arrangement. For the simulation purpose, a single-phase water was used as working fluid with variable thermophysical properties. The present configuration has operated for Reynolds number =100-500, heat flux of 500 kW/m2. The step variation of 100 µm, 200 µm and 300 µm has been considered. It was observed that with increase in step size, the heat transfer augmentation also increases. However, at higher Reynold number, the present studies does not provide effective results in terms of sustainability.

    Abstract: Sustainable construction materials for resource efficiency and environmental effect have grown in popularity .Coconut shells, a waste product of the coconut industry, are plentiful in tropical climates. They are lightweight and permeable, making them an attractive alternative to coarse aggregates. Coconut shells can reduce trash disposal and gravel and sand use by adding them to concrete mixtures. Coconut shell aggregates improve concrete’s mechanical strength and durability, although at a lesser rate than conventional aggregates. Coconut shell replacement depends on particle size, surface properties, and curing conditions. Coconut shells with concrete improve thermal insulation, density, and acoustics. In this investigation compressive and flexural strengths of Grade M20 has been studied by replacing natural coarse aggregates with coconut shells at 0%, 10%, 20% and 30% by weight at curing intervals of 7,14 and 28 days. Cubes and beams were casted and then tested and the tests revealed that coconut shells can be used upto 10% in replacement of natural aggregates imparting a strength almost equivalent to conventional concrete.
