PRE-STRESSED CONCRETE SLEEPERS

During concrete sleeper manufacturing, the steel reinforcement is subjected to a high tensile stress. This stress is then utilized to induce in the concrete compressive stresses which will be directly opposite to those tensile stresses produced by the external forces imposed on the sleeper. A high-tensile steel is used and the value of the applied force is calculated so that the advantage of pre-stressing is retained permanently in the sleeper. The tensile stresses by the process of pre-stressing are so reduced as to permit dispensing with all shear reinforcing, which results in a saving of steel of between 70 percent, and 80 percent, over the ordinary reinforced concrete sleeper.
