The article is devoted to the analysis of a new technology for the production of railway sleepers made of sulfur concrete, which is an alternative to traditional cement concrete. The article discusses the physical and chemical principles of manufacturing the material, where technical sulfur acts as a thermoplastic binder instead of cement and water. The article also highlights the environmental benefits of this material. The article provides technical specifications for sulfur concrete sleepers, including their ability to withstand 5 million cycles of loading, their hydrophobicity, and their chemical resistance.

Sulfur concrete (seroconcrete) is a promising composite material obtained from the melt of technical sulfur and mineral fillers, mainly man-made waste. The article discusses the composition, production technology, raw materials, physical and mechanical properties, and applications in the Arctic, hydraulic engineering, and transport construction. The relevance of this research is due to the disposal of thousands of tons of sulfur annually, which addresses environmental issues and reduces costs.
