Type of Cement Used for Road Pavements
Introduction
Road pavements are an essential part of modern transportation infrastructure. The pavement serves as a stable and durable surface for vehicular traffic. The pavement's construction requires a binding material, which is usually cement. The type of cement used for road pavements is essential in determining the pavement's performance and longevity.
Ordinary Portland Cement
Ordinary Portland Cement (OPC) is the most commonly used cement for road pavements. OPC sets and hardens quickly, making it ideal for constructing pavements. The cement has a high compressive strength, which is essential in withstanding the weight of heavy vehicles. OPC is also readily available and affordable, making it an ideal choice for road pavement construction.
Rapid Hardening Cement
Rapid Hardening Cement (RHC) is another type of cement that can be used for constructing road pavements. RHC sets and hardens faster than OPC, making it an excellent choice for constructing pavements that need to be opened to traffic quickly. However, RHC is more expensive than OPC and not readily available, making it less commonly used.
Low Heat Cement
Low Heat Cement (LHC) is another type of cement that can be used for constructing road pavements. LHC releases less heat during the hydration process, making it ideal for constructing large pavements. The cement is also more durable and resistant to chemical attacks, making it an excellent choice for constructing pavements in harsh environments.
Blast Furnace Slag Cement
Blast Furnace Slag Cement (BFSC) is a type of cement that is made by combining blast furnace slag with OPC. BFSC has a lower heat of hydration and is more resistant to sulfate attacks, making it ideal for constructing pavements in areas with high sulfate content. However, BFSC is more expensive than OPC and not readily available, making it less commonly used.
Conclusion
In conclusion, the type of cement used for road pavements is essential in determining the pavement's performance and longevity. Ordinary Portland Cement is the most commonly used cement for road pavements due to its availability, affordability, and high compressive strength. However, other types of cement, such as Rapid Hardening Cement, Low Heat Cement, and Blast Furnace Slag Cement, can also be used depending on the specific pavement's requirements.
