Concrete sleepers are the basic materials used for laying railway lines and are an important material indispensable for railway superstructures. Their functions are: fixing the gauge of railway tracks, bearing the weight of rails and passing vehicles, making the rail pressure load evenly dispersed and transmitted to the roadbed, and keeping the line stable and unobstructed. The characteristics of concrete sleepers are good stability, long service life, and low maintenance and repair costs; of course, there are always two sides to everything. The bad side is that it is heavy, has poor elasticity and insulation performance, and a buffer insulation pad must be provided at the bottom of the rail.

Conventional specifications of cement sleepers

Advantages of concrete sleepers:

1. Raw materials are easily available and widely circulated, which can meet the needs of reducing production costs;

2. Concrete sleepers have a long service life, high stability, small maintenance workload, and much lower damage and scrap rates than wooden sleepers;

3. The sleepers have large longitudinal and lateral resistance, provide sufficient stability, and have the advantages of good elasticity, easy processing, and convenient use;

4. Concrete sleepers need to be steam-demolded in one step, with a smooth appearance, hard inside, and contain multiple threaded steel bars.

After long-term use, cement sleepers will be seriously worn out. They need to be maintained in time and replaced when necessary.

Precautions for concrete sleepers

1. Avoid moisture and hardening

For cement sleepers that have become damp or hardened, they must be sieved before use. The sifted lumps are generally used for masonry mortar or plaster mortar for secondary projects after rubbing or grinding. For cement lumps that powder when touched or pinched, the strength grade can be appropriately reduced.

2. Avoid freezing at negative temperatures

After cement or mortar is mixed, if it freezes, the cement cannot be hydrated, and the water freezes and expands, then the cement sleeper will be damaged from the outside to the inside, so the construction should be strictly in accordance with the "Winter Construction Regulations for Construction Projects".

3. Avoid high temperatures

For places with high temperatures for a long time, refractory bricks can be used to isolate and protect cement sleepers. In case of higher temperatures, special heat-resistant cement should be used for pouring, or a standard amount of finely ground heat-resistant materials can be added to the mud.
