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 6452: 1989 for high alumina cement.

IS 6452: 1989 covers high alumina cement for structural use. This standard specifies the manufacturing requirements of high alumina cement (HAC) and the specific requirements for its use as a structural building material in our country's colder regions (constantly 18°C or below). Its application as a refractory cement is not covered.

This cement shall be produced from aluminous and calcareous materials by fusing or sintering, and the resulting clinker shall be ground to produce cement meeting this standard. Additional than water, no other materials may be added during the cement grinding process. The total alumina content (ALz03) determined in line with IS 4032: 1985 shall not be less than 32 percent by mass.

When tested according to the methods specified, high alumina cement shall meet the 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.
