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 is suitable for reinforced cement concrete slab ordinary portland cement or Portland Pozzolana Cement?
Ordinary Portland cement is suitable. As per IRC 21, Portland Pozzolana Cement is limited for Plain Concrete only.
Difference between opc and ppc?
Ordinary Portland Cement, also known as OPC, is a type I cement that does not only harden, but also becomes water-resistant once it cures. Pozzolanic Portland Cement, or PPC, is a type IV cement that includes a mixture of a pozzuolanic material, which can increase the strength of the concrete and reduce the amount of OPC used.
Difference between ordinary Portland cement and puzzalona Portland cement?
OPC - Ordinary Portland cementOPC - Materials used - Argillaceous and calcareous materialsPPC - Portland Pozzolona CementPPC - OPC + Pozzolonoc materials(fly ash, volcanic ash, pumicite at the time of grinding).
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 are the chemical properties of sulphate resistant cement?
Advantages of using sulphate resisting cement,It is used in marine constructionUsed 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 is src cement?

Which type of cement used in construction of canal lining?
sulphate resistant cement
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.
What are the different types of cement?
Type-I - Ordinary portland cement used in general constructionType-II - Portland pozzolana cement , moderate heat of hydrationType- III - Rapid hardening cement used for quick setting worksType-IV - low heat cement, low heat of hydrationType-V - Sulphate resisting cement used in sewage linings,marine construction.
What is the difference between portland cement and type II cement?
The portland cement is used in general construction.The type-II cement is used in general concrete construction exposed to moderate sulphate action. i.e.,Concrete to be used in marine conditions.Concrete to be used in the construction of sewage treatment works.
What are the various types of Ordinary Portland Cement?
The various types of ordinary portland cement are,Ordinary portland cement 33 gradeOrdinary portland cement 43 gradeOrdinary portland cement 53 grade
What kind of rocks are in Portland cement?
Kinds of portland cement:Type - 1 - Ordinary portland cementType - 2 - Portland pozzolana cementType - 3 - Rapid hardening cementType - 4 - Low heat cementType - 5 - Sulphate resisting cement.
What is the strength of portland pozolona cement birla Shakti Indian cement company crack resistant cement after 28 days of curing?
Because this cements this cements water absorps maximum.
Should Portland cement be capitalized?
According to the Portland Cement Association, portland cement should not be capitalized.
How does Portland cement differ chemically from other cement?
I assume you are contrasting portland cement with fly ash to portland cement with powdered slag? (Fly ash is from coal furnaces, powdered slag is from oil-burning furnaces). Slag is very similar to portland cement, and can be used to cheaply replace up to 50% of portland cement in concrete. This is less expensive, and the slag makes the hardened concrete more resistant to de-icers. Fly ash is not similar to portland cement, but is also good to resist de-icers. But since fly ash is not similar to portland cement, only 20 to 30% of portland cement can be replaced by it. The main difference in chemistry are the amounts of oxygen-containing elements. (Called 'oxides'). For example, portland cement has 65% of C2O, Slag cement has 45%, and Fly ash contains 25% For SiO2 portland cement 20%, Slag cement 33%, and Fly ash 37% For Al2O3 portland cement 4%, Slag cement 10%, Fly ash 16%. There are other very minor differences in chemistry.
