Railway Sleeper Manufacturing Cement (53-S Grade OPC)
Home Contact Us Search Site Map

53-S Grade OPC Cement is Special Grade Cement required for manufacture of Concrete Sleepers for Indian Railways.

ADVANTAGES
Its negligible chloride content protects against corrosion
High fineness enhances workability with proper water cement ratio, ensuring water cement ratio, density, compactness, smooth, waterproofed and durable concrete.
Lower percentage of C3A resulting in low heat of hydration, reduces cracks and hence leading to greater durability.
It is economical due to its high compressive strength, which appreciably reduces the cement consumption in concrete mix design.
High early strength enables improved mass production cycle of Railway Sleeper
IDEAL APPLICATIONS
Precast, prestressed concrete sleepers
R.C.C. bridges
Precast concrete element like tiles, pipes, grills, door frames and manhole covers.
Prestressed electric poles.
