QUALITY CONTROL MEASURES IN THE PRODUCTION OF PRESTRESSED CONCRETE SLEEPERS

Precasting ensures consistent quality and improved performance of finished components owing to stringent quality control measures generally adopted during their production. Among the many precast concrete components used in buildings and other structures, the prestressed concrete monoblock railway sleeper merits special attention, because of the very high degree of quality control required to be exercised during its production. The paper briefly describes the influence of some of the major parameters on the production and testing of prestressed concrete sleepers.
