In this post, we are going to check out what are the Indian Standards for various grades of cement as per Is-456: 2000 edition.
1. IS : 269 Specifications for 33 grade Ordinary Portland Cement.
Considered a low-strength cement, typically used for plastering, masonry, and non-structural applications where high strength isn’t required.
2. IS : 8112 Specifications for 43 grade Ordinary Portland Cement.
Commonly used in residential construction, offering good strength and workability for most building projects.
3. IS : 12269 Specifications for 53 grade Ordinary Portland Cement.
Preferred for high-strength applications like large structures, heavy-duty construction, or situations where quick setting times are needed.
4. IS : 12330 Specifications for SRPC (sulphate resistant portland cement).
Sulfate resistant cement (SRC) is a type of Portland cement that is resistant to the damaging effects of sulfates in water. It’s used in construction projects where sulfates could damage conventional cements. It is used In seaport engineering, In water conservancy engineering, In underground construction, and In building foundations where the soil has high sulfate aggression.
5. IS : 1489 Specifications for PPC (Portland pozzolana cement).
Portland Pozzolana Cement (PPC) is a type of blended cement that contains Portland cement clinker, gypsum, and pozzolanic materials. It’s used in many construction projects, including dams, sewage pipes, and marine structures.
6. IS : 455 Specifications for PSC (Portland slag cement).
Portland Slag Cement (PSC) is a cement made by mixing Portland cement with blast furnace slag. It’s used in a variety of construction projects, including dams, roads, and marine structures.
7. IS : 6452 Specifications for HAC for structural use (high alumina cement).
This Cement is widely used in marine construction and sewer infrastructure due to its rapid hardening and high strength.
It is utilized in refractory concrete for applications requiring high strength at elevated temperatures.
8. IS : 6909 Specifications for SSC (super sulphated cement).
Super sulphated cement (SSC) is an eco-friendly cement made from industrial by-products like ground granulated blast furnace slag (GGBFS). It’s also known as sulfate activated slag cement.
9. IS : 8041 Specifications for RHPC (Rapid Hardening Portland cement).
Rapid Hardening Portland Cement (RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development, compared to using Normal Cement. The improved early performance of RHPC is achieved principally through increased product fineness.
