  • pre stressed concrete sleepers crushing - Matériel -

    pre stressed concrete sleepers crushing . A concrete cube taken from the sleepers is tested in a 'cube crushing test' which ascertains the strength of the concrete. These cubes taken from one end of each line must reach a minimum strength of 32N per sq. metre before detensioning is carried out.

    Design Wheel Load on Concrete SleepersCalculating The Design Moments on SleepersRailway Sleeper TestsSummaryThe design wheel load, also known as dynamic support-point force, is the force that acts on the sleeper and that, in turn, produces the design moment. In bending tests, the concrete sleeper must be able to withstand this design moment without the formation of cracks. The design load is calculated from the static wheel load Q of the train, which makes up 50% of the axle load: i.e., 173.5 kN.This force is furthermore influenced by the dynamic factor γv, which takes the speed and faults in vehic...
