The most important difference between OPC and SRC clinker is their sulfate resistance. OPC clinker is susceptible to sulfate attack in regions with high sulfate content in the soil or groundwater. This can cause the concrete to deteriorate and weaken over time, reducing its lifespan. On the other hand, SRC clinker has a high sulfate resistance due to its unique chemical composition and microstructure. It can prevent the formation of harmful sulfate compounds, making it ideal for use in construction projects in regions with high sulfate content in the soil or groundwater.

Another difference between OPC and SRC clinker is their production process. The production process for SRC clinker is more complex than that of OPC clinker. SRC clinker requires careful selection of raw materials and precise control of temperature and chemistry in the kiln to achieve its high sulfate resistance. As a result, SRC clinker is often more expensive than OPC clinker.

In terms of applications, OPC clinker is commonly used in a wide range of construction projects due to its versatility and cost-effectiveness. It has a high compressive strength and predictable setting time, making it ideal for use in buildings, bridges, and roads. On the other hand, SRC clinker is commonly used in marine structures, foundations, and other below-ground structures that are exposed to sulfate-rich water or soil.

In conclusion, while OPC and SRC clinker may seem similar, their differences in sulfate resistance, production process, and applications make them suitable for different construction projects. If you are planning a construction project, it’s important to consider the sulfate content in the soil or groundwater and the specific requirements of your project to determine which type of clinker is most suitable for your needs.
