Abstract: This study aims to determine the physical and chemical properties of blends consisting of fish oil methyl ester (FOME), diethyl ether (DEE), and butanol. Understanding these properties is crucial for assessing the suitability of such blends as alternative fuels for internal combustion engines. Experimental investigations are conducted to analyze parameters such as density, viscosity, flash point, cetane number, calorific value, cold flow properties and Fatty Acid Methyl Ester analysis. The results of this study provide comprehensive insights into the characteristics.....

Abstract: Background: The aim of this work is to evaluate the possibility of improving the mechanical properties of modified bituminous concrete by partially replacing the bitumen with used tyre powder, the main component of which is synthetic rubber. The first step in this investigation was to improve the performance of a conventional class 60/70 bitumen using used tyre powder. Secondly, to formulate a semi coarse bituminous concrete (BBSG 0/10) with our modified binder. The aim was to highlight the mechanical behaviour of class 50/70 bitumen and semi-textured bituminous concrete (BBSG 10) formulated using the modified binder.....

Abstract: Response Surface Methodology was used to examine the percentage of heavy metal removal from a sanitary landfill site utilising a lateritic soil-geopolymer composite. By Using the model, the lateritic soil geopolymer composite's adsorption potential was enhanced. The applicability of the employed model to predict the adsorption state is supported and confirmed by the good agreement between the observed and anticipated values of the removal efficiency. The applied models showed that all three of the components examined had an impact on the removal of heavy metals....

Abstract: Now a day's fine aggregate(sand) and coarse aggregate is very expensive, so that by using admixtures like egg shell powder and sea shells as partial replacement in fine aggregate, coarse aggregate would give better saving and environment free. Seashell contains large amount of calcium content, and the rough texture of the seashell makes suitable for the partial replacement of coarse aggregate in concrete which provides economically alternative for not only the coarse aggregate in concrete but also the materials used in concrete such as sand and cement also.Eggshellr.....

Abstract: Plastic pollution is the most ignored problem which the world facing currently. So, In what ways can Architecture be a solution for plastic pollution?How and which plastic waste can be integrated into construction materials, And will they be sustainable for the life and Eco-system of the world? Plastic waste has been accumulating since the year of its invention. Besides its revolutionary properties plastic has ended as a single-use material. As an architect, it is responsible to understand the global problems and creating habitats or spaces that are self-sustainable or helpful for the Eco-system. Architectural awareness about the Eco-plastic material should take place by encouraging.....

Abstract: The use of vinyl ester resin as a matrix in polymer composite materials for use in civil engineering applications is covered in this study. The research starts out by going over the growing trend of composite development and applications in civil engineering, as well as the associated factors. Because of their low life cycle costs, ease of application, and customizable performance characteristics, their employment in the restoration of concrete structures has expanded recently. Due to these qualities as well as the effectiveness of structural rehabilitation techniques, new lightweight structural ideas that make use of all FRP systems or new FRP concrete composite systems have.....
