Indian StandardSPECIFICATION FOR

SULPHATE RESISTING PORTLAND CEMENT

o. FOR E WORD

0.1 This Indian Standard was adopted by theBureau of Indian Standards on 12 May 1988,after the draft finalized by the Cement andConcrete Sectional Committee had been approvedby the Civil Engineering Division Council.

0.2 Sulphate resisting Portland cement is a typeof Portland cement in which the amount oftricalcium aluminate is restricted to an acceptablylow value." This cement should not be mistakenfor supersulphated cement, which is produced byintcrgrinding or intimately blending a mixture of

"granulated blast furnace slag, calcium sulphateand a small amount of Portland cement or Port­land cement clinker or any other source of lime.

Sulphate resisting Portland cement can beused for structural concrete wherever ordinaryPortland cement or Portland pozzolana cementor Portland slag cement are useable under normalconditions. Use of supersulphated cement is,however, generally restricted where the prevailingtemperature is below 40°C. The later is notrecommended for producing steam-curedproducts.

No material shall be added after burningother than gypsum (natural 01" chernical ] or

the concrete is exposed to the risk of deteriora­tion due to sulphate attack, for example, in cont­act with soils and ground waters containingexcessive amounts of sulphates as well as forconcrete in sea water or exposed directly to seacoast.

0.3 Mass of cement packed in bags and thetolerance requirements for the mass of cementpacked in bags shall be in accordance with therelevant provisions of the Standards of Weightsand Measures ( Packaged Commodities) Rules,1977 and A-l.~ (see Appendix A for informa-tion). Any modification to these Rules in respectof rolei ance on mass of cement would automati­cally apply to this standard.

0.4 For the purpose of deciding whether aparticular requirement of this standard is compli­ed with, the final value, observed or calculated,expressing the result of a test, shall be roundedoff in accordance with IS : 2-1960·.
