ECO-FRIENDLY RAILWAY CONCRETE SLEEPER

초록

There have been various research activities to develop the green vehicles in railway industry which reduce the energy consumption such as high-speed train, tilting train, light rail transit, wireless tram and so on. On the other hand, researches on the eco-friendly railway infrastructure have been very limited to deal with the important social issue of reducing CO2 emissions. Therefore we have look at the concrete sleeper very closely, started to find the alternative materials, and thus developed the eco-friendly railway concrete sleeper. Based on the research results, steel slag is suitable alternative concrete ingredients to cement and natural resources for railway infrastructure applications. Eco-friendly railway concrete sleeper can contribute to reduce carbon dioxide (CO2) emissions in railway concrete infrastructure.
