Integrating fiber with new cement trends to create a greener future for sustainable concrete

Abstract

The need for innovation in the construction sector is increasingly pressing, propelled by rising environmental issues and the ongoing quest for structural efficiency. This study investigates the transformational potential of fiber-reinforced concrete (FRC), analyzing its ability to improve mechanical performance and promote environmental sustainability. By using diverse fibers, including natural, synthetic, and industrial waste fibers, FRC enhances qualities like as tensile strength, fracture resistance, and durability while promoting more sustainable building techniques. This research carefully explores current improvements in the processing and handling of various fibers and assesses their effects when integrated into concrete. Particular emphasis is placed on the use of recovered industrial by-products, including slag, fly ash, and recycled plastics, in conjunction with natural fibers such as bamboo, kenaf, and flax. These materials are recognized for both augmenting the structural integrity of concrete and substantially decreasing the carbon footprint of construction by lowering dependence on virgin resources and encouraging the recycling of industrial waste. Experimental investigations and life cycle evaluations were performed to measure the improvements in performance and sustainability provided by FRC. The study results indicate that FRC has enhanced durability and performance attributes, making it a suitable choice for both structural and non-structural applications. Moreover, the incorporation of sustainable fibers has shown a decrease in greenhouse gas emissions, consistent with international sustainability objectives. Nonetheless, the implementation of FRC encounters obstacles pertaining to the inconsistency of fiber characteristics, economic viability, and industrial scalability. Confronting these obstacles via continuous research and interdisciplinary cooperation is essential for the widespread adoption and use of FRC in the construction sector. This study emphasizes the significance of new materials, such as fiber-reinforced concrete, in promoting sustainable building methods, illustrating its potential to profoundly influence the future of construction regarding environmental responsibility and structural efficacy.
