BIS CERTIFICATION FOR SUPERSULPHATED CEMENT
In this competitive scenario, it isn't easy to survive in the market without a standard quality and certified product. BIS license may also be required to sell products in the Indian market.
To get BIS certification and produce a standard quality product, the manufacturer must ensure that their product must follow the specified Indian standard.
Let's take a closer look at IS 6909: 1990 for supersulphated cement.
IS 6909:1990 covers supersulphated Cement. This standard specifies the requirements for the composition, production, and testing of supersulphated cement. Super-sulfated cement has various advantages over ordinary Portland cement, including low hydration heat evolution, excellent sulphate resistance, and the use of less clinker and more gypsum.
Supersulphated cement shall be made by intergrinding or intimately blending a mixture of granulated blast furnace slag, calcium sulphate, and a small amount of 33 grade ordinary Portland cement, Portland clinker, or any other lime source. The mixture's dry granulated blast furnace slag component must be at least 70% by mass. The cement must be ground finer than 33 grade ordinary Portland cement, and the manufacturing method must ensure intimate blending of its constituents.
When tested according to the methods specified, supersulphated cement shall meet the chemical and physical requirements specified in the standard. The manufacturer must ensure that the cement meets the requirements of this standard. A laboratory shall be adequately maintained, in which the various tests shall be carried out according to the methods specified in the standard.
The following test shall be carried out for supersulphated cement in accordance with the method specified.
- Setting time
- Compressive Strength
- Transverse Strength Test
- Chemical requirement
Packing of supersulphated Cement shall be done as per IS 6909:1990. Labelling and marking shall be done in accordance with the standard. The BIS Standard Mark shall be printed on each bag or drum of supersulphated Cement or on the label applied to it, provided that the material in each bag or package to which the mark is thus applied meets the specification. The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark. The BIS grants a license based on a successful assessment of manufacturing infrastructure, quality control and testing capabilities, and production process.
