What Is High Alumina Cement?
Not all construction projects work with ordinary cement. The industry and structural applications require some materials that are capable of withstanding high temperatures, severe chemicals and extremely hostile environments. That is precisely where High Alumina Cement (HAC) will come in as a medium of choice. High Alumina Cement is a special form of hydraulic cement, which is produced by fusing or sintering the mixture of limestone and bauxite under very high temperatures. This cement has a high alumina content that contributes to the high level of properties, including fast development of strength, high resistance to high temperatures, and being highly resistant to chemical attacks such as sulphates and weak acids. It finds extensive applications in refractory concrete, furnace lining, chimneys and sewage structures among industrial applications.
What Is IS 6452:1989?
The Bureau of Indian Standards (BIS) has introduced a special Indian Standard of High Alumina Cement by the name of Indian Standard of High Alumina Cement, referred to as IS 6452:1989. This standard stipulates the technical need, physical and chemical characteristics and testing regimens that all High Alumina Cement products have to fulfil prior to the products being legally sold in India. This standard was published in 1989 and has remained the reference on quality in the country so far as HAC is concerned. It addresses the major parameters that include alumina content, compressive strength, setting time, fineness, and soundness. To sell High Alumina Cement in India legally under the IS 6452:1989, any manufacturer or importer of the product must possess a valid BIS ISI Mark licence.
Why is BIS Certification a Requirement with high Alumina Cement?
High Alumina Cement is now covered under the BIS Compulsory Certification Scheme by the Government of India, and therefore, it is a legal requirement for all manufacturers, importers, and traders to have an operating BIS licence under the IS 6452:1989 and sell the product in India. This requirement is obvious by the fact that High Alumina Cement finds utility in the most crucial industrial operations in which any form of compromised quality may cause severe structural losses and safety risks. When the quality of HAC is not good in a furnace lining, a chemical plant, or a high-temperature refractory structure, the resultant fallout may be highly hazardous and expensive. The BIS ISI Mark on a product provides the buyers, engineers and project managers the assurance that the cement has been tested on its own and is up to the standards established under IS 6452:1989. The sale of High Alumina Cement by way of a licence without a genuine BIS licence is a contravention of the BIS Act, 2016, which may be severely punished by the law.
Major Technical Requirements Under IS 6452:1989
In order to obtain the BIS ISI Mark certification of High Alumina Cement, the manufacturers should make sure that their product meets all technical tests that are required under IS 6452:1989. The cement should not contain less than 32 per cent alumina content (Al2O3). The cement should have the required compressive strength at 1 day and 3 days as stipulated in the standard, which is one of the most significant features of the cement; it gains strength quickly. The setting time should not be less than 2 hours, and the setting time should not be more than 9 hours. The cement fineness, which is determined by the Blaine method or sieve test, should have a minimum limit. The soundness, which is checked by the Le Chatelier method, should also be kept at acceptable limits. All these tests should be done in NABL-recognised or BIS-recognised laboratories, and the results should always be in line with IS 6452:1989 to be awarded and maintain the BIS licence.
Application to BIS Certification in IS 6452:1989
The awarding of the BIS ISI Mark of High Alumina Cement is a process. The manufacturer will have to first link his/her name to the BIS Online Portal and make a formal application with all the necessary documents, such as factory and plant description, flow of manufacturing process, specifications of raw materials, quality control records, and latest test results of approved laboratories. BIS will then make a visit to the factory by a BIS officer to determine the availability of the right equipment, processes, and quality management systems at the manufacturing unit. Upon clearing the inspection and passing all the tests on product samples by the IS 6452:1989, BIS issues the licence of ISI Mark that lasts one year and has to be renewed periodically.
Advantages of BIS Certification and the BIS Certification support offered by Induce India
Becoming BIS certified based on IS 6452:1989 has more than legal compliance, real business value. A product with the BIS ISI Mark immediately builds credibility among the industrial buyers, project consultants and government procurement agencies. The ISI Mark is a minimum requirement for most of the large government and private sector projects that have critically utilised High Alumina Cement. The certification is also relevant to help the manufacturers minimise the rate of product rejection, enhance the internal quality systems and establish a greater brand name in the local and expatriate markets.
Coming out of it, however, without the appropriate guidance, the BIS certification process may prove to be complex and time-consuming. One such reliable certification consultancy is Induce India, which provides full end-to-end assistance in BIS ISI Mark certification in accordance with IS 6452:1989. Since the application submission and document preparation up to the skilful arrangement of laboratory tests, factory audit support, and renewing the licence, the professional team of Induce India handles all steps. They understand the BIS procedures and IS 6452:1989 requirements well, thus making sure that your product and facility are all prepared before the inspection and therefore save you time, efforts and unwarranted delays.
Conclusion
