Abstract: The growing demand for sustainable and durable construction materials has spurred significant advancements in the development of fiber-reinforced rubber composites within civil engineering. This study investigates the integration of recycled tire rubber with various fiber reinforcements specifically carbon, glass, and synthetic fibers to enhance the mechanical properties, durability, and eco-sustainability of concrete and asphalt composites. The composites were prepared at varying fiber and rubber content (5%, 10%, and 15%) and tested for flexural strength, compressive strength, impact resistance, and durability under freeze-thaw cycles and traffic load simulations. The results showed that fiber-reinforced rubber composites exhibit significantly improved mechanical performance compared to conventional concrete and asphalt, with increased flexural strength, impact resistance, and long-term durability. An environmental impact assessment using Life-Cycle Analysis (LCA) revealed a marked reduction in CO2 emissions, energy consumption, and landfill waste due to the use of recycled tire rubber. The cost-benefit analysis demonstrated that although fiber-reinforced rubber composites entail higher initial material costs, the long-term savings due to reduced maintenance and longer service life make them a cost-effective alternative in infrastructure applications. Furthermore, the study highlights the potential for these materials to contribute to sustainable development in civil engineering by promoting circular economy practices and recycling. The findings underscore the transformative potential of fiber-reinforced rubber composites in achieving resilient, sustainable, and durable infrastructure, while also addressing critical environmental and economic challenges in modern construction practices. Future research is needed to optimize production processes, reduce costs, and further explore applications in high-performance pavements, earthquake- resistant buildings, and soil stabilization.

Abstract: Off-grid communities face significant challenges in achieving reliable and sustainable energy access. This paper proposes a novel hybrid energy system consisting of solar power, wind energy, and energy storage, optimized using artificial intelligence (AI) techniques. The aim is to enhance energy generation efficiency, improve system reliability, and minimize operational costs. We present a detailed analysis of AI-driven optimization algorithms that forecast energy generation, balance storage capacities, and manage energy consumption in real time. Through simulations, the proposed system is evaluated under various environmental conditions, demonstrating its potential to provide a stable, cost-effective energy solution for off-grid areas. Additionally, the study assesses the economic and environmental benefits of integrating renewable energy and advanced storage systems, showing a significant reduction in fossil fuel dependency. The results indicate that AI-optimized hybrid systems can offer an efficient and sustainable alternative to conventional energy solutions, contributing to the global transition to renewable energy.
