FOREWORD

This Indian Standard was adopted by the Bureau of Indian Standards on 20 June 1989, after the draftfinalized by the Cement and Concrete Sectional Committee had been approved by the Civil EnaineeringDivision Council.

The requirements of low heat Portland cement were earlier covered in IS'269 : 1976 'Specification forordinary and Jow heat Portland cement ( third revision )' which in addition, covered the requirementsof ordinary Portland cement. Since the Sectional Committee decided to bifurcate the standard, therequirements of low heat Portland cement have now been covered in a separate specification.

This specification covers the requirements of Jow heat Portland cement as was given in IS 269 : 1976with the various amendments published from time to time.

Low heat cement is particularly suited for makin, concrete for dams and many other types of water­retaining structures, bridge abutments. massive retaining waUs, piers and slabs, etc. In mass eonerenng,there is often considerable rise in temperature because of the heat evolved as the cement sets andhardens, and the slow rate at which it is dissipated from the surface. The shrinkage which occurs ODsubsequent cooling sets up tensile stresses in the concrete which may result in cracking. The use oflow heat cement is advantageous since it evolves Jess heat tban ordinary Portland cement.

Mass of cement packed in bags and the tolerance requirements for the mass of cement packed in bapshall be in accordance with the relevant provisionsof the.Standard8 of Welghtl QIIdMeQSUr~8 ( PackagedCommoditl6s ) Rulel, 1977and 8-1.2 (see Annex B for information). Any modification in thaerules in respect of tolerance on ma.1 of cement would apply automatically to this standard.

Thil standard contains clause 11.4.] which gives option to the purchaser and clauses 6.5, '.2.1 and ,.3which call for agreement between the purchaser and the lupplier.

In the formulation of this standard, considerable assistance haa been rendered by the National Councilfor Cement and Building Materials, New Delhi as many of the chanaeaare based on the studies carriedout by them.

The composition of the technical committee responsible for the formulation of this standard is livenin Annex C.

For the purpose of deciding whether a particular requirement of tbi.· standard is complied with, thefinal value, observed or calculated, expressing the result of a test or analysis, ahall be rounded off inaccordance with IS 2 : 1960 'Rules for rounding off numerical values ( revised )'. The ·number ofsignificant places retained in the rounded off value ahould be the same al that of the .pccified valuein this standerd.

PORTLAND CEMENT, LOW HEATSPECIFICATION

1 SCOPE

1.1 This standard coven the manufacture andchemical and physical requirements of low heatPortland cement for use where low heat of hydra­tion is required, as in mass concrete for dams.

2 REFERENCES

2.1 The Indian Standards listed in Annex A arenecessary adjuncts to this standard.

3 TERMINOLOGY

3.1 For the purpose of this standard, the defini­tions given in IS 484S : 1968 shall apply.

4 MANUFACTURE

4.1 Low heat PortJand cement shall be manu­factured by intimately mixing together calcareousand argillaceous and!or other silica, alumina oriron oxide bearing materials, burning them at aclinkeriDI temperatureand grinding the resultantclinker so as to produce a cement capable ofcomplying with this specification. No materialshalJ be added after burning, other than gypsum

( natural or chemical) or water or both, and notmore than one percent of air-entraining agents orother agents which have proved not to be harmful.

NOTE - Chemical gypsum shall be added providedthat the performance' requirements of the finalproduct al specified in this standard are met with.

5 CHEMICAL REQUIREMENTS

5.1 When tested in accordance with the methodsgiven in IS 4032 : 1985, low heat Portland cementshall comply with the chemical requirements givenin Table 1 and S.2-

S.2 The percentage of lime, after deduction of thatnecessary to combine with SUlphuric anhydridepercent, shall be:

a) not more than 2·4 ( SiO. ) + 1'2 ( Al~03 )+ 0·65 ( FelOa ), and

b) not Jess than 1·9 ( SiOI ) + 1-2 ( AltO. )+ 0·65 ( Fe~03 ).

NOTE - Each symbol in brackets refers to thepercentage ( by mass of total cement) of the oxideexcluding any contained in the insoluble residuereferred to at 81 No. (Ii) of Table 1.

In the case of reactive allrelates.the use of cement with alkali contem below 0·6 percent expressed as sodium oxide (Na.O), isrecommended. Where, bowever

or cement pozzoJanlc admixture s recommended. -3 The Jlmlt or total chloride content'.in cement for UN in plain and other reinforced concrete structures isbelll' reviewed. Till that time, the limit may be mutually .arced to between the purchaser aDd tbomanUfacturer. .
