Scope, quoted from IS 8041 : 1990 — the 1990 edition in the public archive, not the current IS 8041 : 2026. Read the full standard

The BIS registry lists the current edition as IS 8041 : 2026. The publicly archived copy quoted here is the 1990 edition, so wording and requirements may have changed since. Check the official BIS listing for what is in force.

Where this standard is used on NirmanDost

Listed by product makers

1 product in the NirmanDost catalogue names this standard on its spec sheet — Ramco Superfast (RSF) - Rapid Hardening Portland Cement. That is the maker’s own claim, copied as printed; we have not tested these products against the standard, and a spec sheet can cite the wrong code.
