68 prestressed concrete sleepers. Mono-block prestressed concrete sleepers, which were first employed in the 69 early 40’s, have become essential components in high speed rail track constructions worldwide . [28, 29] 70 The extraordinary development of high speed train networks in Europe and Asia [30], has led to a great 71 number of studies
Oct 01, 2009· Prestressed concrete sleepers are often the main part of the broad gauge rail tracks. The dimensions of the prestressed concrete sleeper are given in Table 1. The typical profile and cross section of the prestressed concrete sleepers at railseat is shown in Fig. 2. The cross-sections of the prestressed concrete sleeper were optimised for
Prestressed Concrete Sleepers are designed to resist dynamic form of loading mainly. Freyssinet developed a sleeper with 2mm diameter wires, wound continuously as a thread, and pretensioned by rods passing through the loops at each end. The principle function of the sleepers is to distribute the wheel loads carried by the rails to the ballast.
Based on this, they developed their own optimized production machines and moulds which are sold internationally. The company offers the full engineering of a sleeper plant. Offer. Full design of prestressed concrete sleepers in accordance with customer’s specifications. Engineering of factory layout and buildings, utilities, etc.

Applications of prestressed concrete are many, especially in recent times, it has been widely used in bridges, buildings, rail sleepers, nuclear vessels, water and other liquid retaining structures etc. Prestressed concrete is a particular form of reinforced concrete in which external prestressing force is applied on the concrete to reduce or
FAILURE of a prestressed concrete beam in bending* is caused initially either by yielding of the steel near the bottom face (Primary tension failure), or by crushing of the concrete near the top face (Primary compression failure). Primary tension failures occur in beams with low steel ratios, whereas primary compression failures are to be expected in heavily reinforced beams; the two types of
His work, however, was connected to universal lines of thought and longings. In 1982, the architect himself explained his efforts in this field before an auditorium filled primarily with engineers interested in precast elements and prestressed concrete similar to what was proposed in the interesting REDECON conference in Bangalore.
Two new and unused sleeper types were tested: BP99 (date of manufacture 30.11.2009, see Figure 2.2) and B97 (13.3.2009). The sleepers had 12 strands 6.5 mm in diameter. Figure 2.2 Concrete sleeper type BP99. Height 185 mm at the centre. 2.4. Used sleepers Three old and used sleeper types were tested: B63, B75 and BV75. Types B63 and B75 (Figure
