Abstract:
In Korea, high-early-strength Portland cement has been used for railway PC (Prestressed Concrete) sleeper to provide high strength and rapid hardening satisfactorily at early period. However, it is fact that carbon dioxide (CO2) emission from the cement production has been recently one of the main social issues. In this study, eco-friendly PC sleeper, which was developed in order to reduce the usage of cement and natural resources (fine aggregate) as main ingredients of concrete, was tested using UTM (Universal Testing Machine) test facility in order to estimate its dynamic performance optionally required by the European Standard. Based on a series of dynamic performance tests, it was found that eco-friendly PC sleeper can be an environmental as well as mechanical alternative to the ordinary PC sleeper.
