BIS CERTIFICATION FOR PORTLAND SLAG CEMENT IS 455:2015

Portland slag cement, commonly known as PSC, is a type of blended cement used in construction. It's made by combining Portland cement clinker, gypsum, and granulated blast furnace slag (a byproduct of the iron and steel industry) in specific proportions. These ingredients are ground together to create a fine powder.

PSC offers several advantages over regular Portland cement. First, it's more sustainable because it utilizes industrial waste (blast furnace slag), reducing the environmental impact of cement production. Second, PSC has improved durability, reduced heat of hydration, and higher resistance to sulfate and chloride attacks, making it ideal for infrastructure projects, marine structures, and areas with harsh environmental conditions.

The slag in PSC contributes to its unique properties, enhancing workability and long-term strength. Its slower rate of strength gain compared to ordinary Portland cement allows for better control during construction.

Portland slag cement is a type of cement that has certain rules and guidelines set for it in a document called IS 455:2015.The Bureau of Indian Standards officially accepted these rules on October 30, 2015, after they were reviewed and approved by a group called the Civil Engineering Division Council. This standard, IS 455:2015, tells us how Portland slag cement should be made and what chemical and physical qualities it should have.

Basically, it explains how this specific type of cement should be manufactured to ensure it meets certain quality standards. This helps in making sure that the cement is reliable and safe for use in construction and other applications.
