摘要： Disclosed is a heavyweight concrete composition using slag byproducts, including: ground granulated blast furnace slag; slow-cooled electric-arc-furnace oxidizing slag or atomized steel slag used as a fine aggregate; a coarse aggregate; water; and a chemical admixture based on 100 parts by weight high-early-strength cement. Thus, the heavyweight concrete composition contains a large quantity of steel slag and blast-furnace slag that are byproducts in iron-making and steel-making processes, thereby remarkably reducing an amount of emission of carbon dioxide and maximizing the recycling of waste resources for preserving the natural environment. As a result, an eco-friendly heavyweight concrete product can be made.

摘要： By supporting a space generated by a settlement of the track bed gravel or asphalt roadbed underneath a concrete rail tie with cylindrical rods, and installing the present invention, one each separately, on the left and right sides of the concrete rail tie, recovery from settlements is automatic, and the response to differential settlements of the left and right rails of the track due to the train load can be easily facilitated, and by installing pressure reducing valves on the upper part of the concrete rail ties, pressure can be reduced while maintaining the track system as is without having to dismantle the concrete rail ties, and accordingly the usability of the concrete rail ties can be improved.
