Combined fibre concrete – Development of a crack-free railway sleeper through the use of a combined fiber-reinforced high-strength concrete

In practice the use of pre-stressed concrete sleepers is often accompanied by cracks-occurrence, such as longitudinal, lateral and shrinkage cracks. At the occurrence of cracks the resistance of sleepers to environmental influences is reduced.By the development of a combined fibre reinforced high-strength concrete, the risk of a formation of micro- and macro cracks can be substantially reduced, whereby the expected lifetime of concrete sleepers can increasing significantly and a costly renovation can be avoided.
