IS 456 : 2000

What this standard covers

This standard deals with the general structural use of plain and reinforced concrete. 1.1.1 For the purpose of this standard, plain concrete structures are those where reinforcement, if provided is ignored for determination of strength of the structure. 1.2 Special requirements of structures, such as shells, folded plates, arches, bridges, chimneys, blast resistant structures, hydraulic...

Listed by product makers

1 product in the NirmanDost catalogue names this standard on its spec sheet — JSW Portland Slag Cement (PSC). 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.
