A COMPARATIVE STUDY ON THE IMPORTANCE OF 3D-PRINTED CONCRETE RAILWAY SLEEPERS COMPARED TO TRADITIONAL TECHNIQUES

Abstract

Abstract- Railway infrastructure plays a vital role in transportation and economic development. One of the key components of railway tracks is sleepers, which provide stability, distribute loads, and ensure track alignment. Traditional railway sleepers, made from timber, reinforced concrete, or steel, often face challenges related to durability, cost, environmental impact, and production efficiency. This study explores the potential of 3D-printed concrete railway sleepers as an innovative alternative to conventional manufacturing techniques. 3D concrete printing offers a promising solution by reducing material wastage, optimizing structural design, and enhancing production speed. This research compares structural performance, cost-effectiveness, and sustainability of 3D-printed concrete sleepers with traditional methods. The study includes an analysis of mechanical properties, durability, and economic viability. Findings indicate that 3D printing technology can significantly reduce production time and material costs while maintaining or even improving the strength and longevity of railway sleepers. The results suggest that implementing 3D-printed concrete sleepers can enhance railway infrastructure efficiency, reduce environmental impact, and provide a more cost-effective solution for the industry.
