Railway Prestressed Concrete Sleeper

Abstract Cracks in railway prestressed concrete sleepers are often caused by the infrequent but high magnitude impact forces. These impact forces are attributed to the wheel or rail abnormalities, e.g. wheel flat, corrugation, dipped joint, etc. The emphasis of this paper is placed on the corresponding fractures of railway prestressed concrete ...

Development of Geopolymer Concrete on Railway PreStressed

Railway prestressed concrete sleeper is an imperative for component of ballasted railway tracks. Its main function is to help distributing axle loading to sub grade and formation. By nature, the concrete sleeper is subjected to sagging moment at the rail seat zone and to hogging moment at the middle section. Although behaviours of concrete sleepers under static loading

Jan 10, 2016 Introduction 1.1 Background The idea of prestressed concrete has been around since the latter decades of the 19th century, but its use was limited by the quality of the materials at the time. It took until the 1920s and 30s for its materials development to progress to a level where prestressed concrete could be used with confidence.
