Do not believe any cement brand that is promoted by a cement dealer or representative from the cement industry; instead, believe the test results of cement as documented by the cement’s test certificate. Every cement brand is already approved by the Bureau of Indian Standards (BIS), but as a cement buyer, you must properly evaluate the cement’s physical and chemical qualities in a concrete laboratory before construction.
There are more than 13 types of cement used in construction industries for various purposes, according to civil engineering. Ordinary Portland Cement, Pozzolana Portland Cement, Portland Slag Cement, and Composite Cement are typically used for residential construction (individual house builders), however these types of cement are made by numerous cement producing companies.
Each cement manufacturer has a technical team that handles customer service for cement quality testing and project site visits. Always request a recent week test certificate from the Technical Service Officer (Civil Engineer) of a separate cement manufacturer, which has been certified by a quality control laboratory. Collect and compare all the recent week test certificates from different cement companies and consult with a quality control engineer to identify the best results about the physical and chemical properties of cement.
But as a result, every cement company’s test certificate from its quality control laboratory, which is present at the cement plant, provides suitable results as per the Bureau of Indian Standards (BIS). So to cross-verify, you should take 3kg of different cement from a different brand (company) that is available near your cement store and test its properties as per your requirements in quality control laboratory, like its fineness, compressive strength, etc.
Also check the expiration date of the cement on the stretcher portion of the cement bag after receiving it, and for satisfaction, ask the cement dealer or distributor for technical service from the respective brand of cement. Every cement brand obeys the standard specifications prescribed by BIS, so all cement provides good strength and durability in our structures, but a cross-check is needed because many local cement dealers sell duplicate low-quality cements that are prepared illegally without authentication.
