“…Acoustic emission technique is now widely used for monitoring and damage detection in various engineering structures, such as concrete shear walls [16], concrete structures [17], railway sleepers [18], dams [19,20], bridges [21][22][23], pavements [24,25] and tunnels [26]. In principle, when a material is subjected to higher load, a burst of energy is released in the form of high-frequency elastic or shear waves from propagating cracks or from plastic deformation [16].…”

“…Firstly, the quality of concrete sleepers is very dependent on the quality of manufacturing process. Two main manufacturing methods are currently used in the world that is a long line method and a single mold method [6,10]. In longline method 100-200 m long formwork tables are used which has 4-8 parallel sleeper molds.…”

“…They withstand static, cyclic, and impact loads of different types, directions and sizes caused by trains, and are affected by support reactions of the ballast [1][2][3][4]. Additionally, sleepers are affected by environmental influences (frost, humidity, temperature variation, aggressive materials) [5] and production processes [5,6]. Furthermore, sleepers need to ensure adequate distance between the rails; evenly distribute loads from the rails to the ballast; maintain adequate inclination of the rails; act as support for the rail; restrict longitudinal, vertical, and horizontal rail displacement; and be resistant to wear.…”

Experimental Research on the Behavior of the Rail Seat Section of Different Types of Prestressed Concrete Sleepers

Nowadays, prestressed concrete sleepers are the most common type of sleepers. In different countries all over the world prestressed concrete sleepers are designed with different shapes, with different types of prestressed reinforcement and arrangements in cross-section. Additionally, different manufacturing methods and techniques are used for prestressed concrete sleepers. These railway members are stiff, durable and can withstand heavy loads. Despite that, damaged or deteriorated prestressed concrete sleepers appear on railway tracks even before the end of their service life. Therefore, there is a need for better understanding of the behavior of different types of prestressed concrete sleepers to optimize their design. The rail seat section of the sleeper is the most affected part of sleeper. Therefore, analysis of experimental results of bearing capacity, cracking, and deformation of the rail seat section of sleeper under static and dynamic loads are provided in this article. Furthermore, different types, diameters, and anchoring methods of prestressed reinforcement were analyzed in this article. Additionally, comparison of experimental results of different types of prestressed concrete sleepers is discussed.

“…Since the 1990s, high-performance concrete (HPC) has been under continuous development, and has been primarily used in high rise buildings, offshore structures, nuclear power plants and long-span bridges [6,7,8]. However, the early age cracking potential of HPC is much higher than that of normal concrete (NC) [9,10,11,12], because of the lower water to binder ratio and higher content of cementitious materials.…”

The early age volume deformation is the main course for the cracking of high-performance concrete (HPC). Hence, the shrinkage behavior and the restrained stress development of HPC under different restraints and curing conditions were experimentally studied in this paper. The method to separate the stress components in the total restraint stress was proposed. The total restrained stress was separated into autogenous shrinkage stress, drying shrinkage stress and thermal stress. The results showed that the developments of the free shrinkage (autogenous shrinkage and drying shrinkage) and the restrained stress were accelerated when the drying began; but the age when the drying began did not significantly influence the long-term shrinkage and restrained stress of HPC; the autogenous shrinkage stress continuously contributed to the development of the total restrained stress in HPC; the drying shrinkage stress developed very rapidly soon after the drying began; and the thermal stress was generated when the temperature dropped. The thermal stress was predominant at the early age, but the contributions of the three stresses to the total restrained stress were almost the same at the age of 56 d in this study.
