Advantages of using sulphate resisting cement,
- It is used in marine construction
- Used in foundations and basements where soil is infested with sulphates.
- Concrete to be used in construction of sewage treatment works.
- Used in fabrication of pipes which are likely to be buried in sulphate bearing soil.

What the sulphate limit in soil after then use sulphate resistant cement?
The sulfate limit in soil after using sulfate-resistant cement is typically around 2,000 parts per million (ppm). Sulfate-resistant cement is designed to withstand sulfate attack in soil, reducing the risk of deterioration due to sulfates. Monitoring sulfate levels in the soil after construction is important to ensure that the limit is not exceeded, as high sulfate levels can compromise the durability of the structure.
Chemistry of SRC cement?
Sulphate resisting cement:Low C3A ContentLow C4AF contentCa(OH)2 + SO2 ---> CaSO3 + H2OIn the above equation water is evolved, so hydration process is continuous in SRC
What is the formula of cement?
4CaO.Al2O3.Fe2O3 (Tetracalcium Alminoferrate)
Is concrete hardening an example of chemical or physical change?
Concrete hardening is an example of a chemical change. When water is added to the cement mixture, a chemical reaction occurs between the water and the cement particles, resulting in a new substance with different properties than the original components.
List the chemical elements in Portland Cement?
Portland cement is mainly composed of four primary chemical elements: calcium, silica, alumina, and iron. These elements combine during the manufacturing process to form various minerals like tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite, which contribute to the cement's properties and performance.
What is src cement?
sulphate resisting cement. Mainly applied for concrete in waste water facilities.
Which type of cement used in construction of canal lining?
sulphate resistant cement
What is Sulphate Resistant Portland Cement?
Sulphate Resistant Portland Cement (SRPC) is a type of cement specifically designed to withstand high sulphate concentrations in soil and water, which can cause deterioration in standard cement. It is produced by modifying the chemical composition of ordinary Portland cement to reduce the amount of tricalcium aluminate (C3A), which is susceptible to sulphate attack. SRPC is commonly used in structures exposed to aggressive environments, such as sewage treatment plants, foundations in coastal areas, and concrete exposed to sulphate-rich soils. Its durability enhances the longevity and performance of concrete in challenging conditions.
What can you add to Portland cement to make it sulphate resistant?
The sulphate resistant cement is made with low C3A content is found to be effective.Such cement with low C3A and comparitively low C4AF content is known as sulphate resisting cement.This cement has a high silicate content.The specification generally limits the C3A content to 5 percent.
What the sulphate limit in soil after then use sulphate resistant cement?

Monitoring sulfate levels in the soil after construction is important to ensure that the limit is not exceeded, as high sulfate levels can compromise the durability of the structure.
What chemical changes will happen when salt water mixed with cement?
magnesium sulphate
Where is sulphate resistant cement used?
Uses:Used in fabrication of pipes which are likely to be buried in marshy region or sulphate bearing soils.Used in marine conditions.Concrete to be used in foundation and basement.Used in the construction of sewage treatment works.
What are the chemical properties of cement?
Portland Cement is made by baking limestone to remove the carbonate, and to this is added some gypsum (to provide sulphate) and diatomaceous earth (effectively a very finely divided silica). When curing, many complex chemicals are formed, the crystals of which give cement its strength. Silicates, sulphates, and carbonates.
