What is SRC Cement?

Manufacturers design Sulfate-Resistant Cement (SRC), also known as Sulphate-Resisting Cement, as a specialized type of Portland cement to withstand exposure to sulfate-rich environments.

Sulfates can be naturally occurring in soils or water or present in industrial and wastewater environments. High sulfate exposure triggers chemical reactions in ordinary Portland cement, forming expansive products, and causing concrete deterioration and cracking.

What is SRC cement and its uses?

Formulators design SRC to resist this sulfate attack and offer durable construction in challenging conditions.

Here are some key features and uses of SRC cement:

1. Sulfate Resistance: SRC is specifically engineered to resist the detrimental effects of sulfate exposure. It contains a lower amount of tricalcium aluminate (C3A) compared to OPC, as C3A is more susceptible to sulfate attack. This reduced C3A content helps prevent the formation of expansive compounds in the presence of sulfates.

2. Durability: SRC cement is often used in applications with paramount durability. Ideal for building in high sulfate zones like sewage plants, coastlines, and industries, it’s apt for concrete structure construction.

3. Marine Construction: Because of its sulfate resistance, people commonly use SRC in constructing marine structures, including piers, jetties, and sea walls, where exposure to seawater and sulfates is prevalent.

4. Underground Structures: SRC is ideal for underground structures like tunnels and basements, where soil conditions may contain sulfates that could potentially damage conventional concrete.

5. Chemical Plants: Industries such as chemical processing and petrochemical plants often use SRC in their construction projects because of the potential exposure to sulfates from chemical processes and wastewater.

6. Sewer Systems: SRC is a preferred choice for the construction of sewer pipes and manholes, as it can resist the corrosive effects of sulfate-rich sewage.
