POIlEWORD

This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after thedraft fiaalized by the Cement and Concrete Sectional Committee had been approved by the CivilEn.ineering Division Council.

As a standard fine auregate used for assessing the quality of cement. standard sand plays a veryimportant role in the cement industry. The importance of a standard .sand in industrial economy isevident from the fact that it is required not only as a testing material in the cement industry but alsoas a standard material to' study the properties of other building materials like lime and pozzolanas,various admixtures to cement and also as a standard material for determining the abrasive resistanceof different substances, such as building stones. Till the year 1955, the country's requirements forstandard sand were met by importing Leighton-Buzzard sand from the United Kingdom. The difficul-ties and expense of importing thisstandard sand from UK led to an investigation to replace Leighton-Buzzard sand by an Indian Standard sand.While formulating the standard for Portlandcement, the Committee also felt the necessity of establish-ing an indigenous standard sand as early as possible. As.a result of extensive survey and research carriedout by many organizations, namely, Geological Survey of India; Industrial Research Bureau; NationalTest House; Concrete and Soil Research Laboratory, Chepauk, Madras; Hirakud Research Station;Hyderabad Engineering Research Laboratory; the laboratories of the Associated Cement CompaniesLtd; and Dr LaIC. Yerman, it was found that the white variety of sand available at Ennore, MadrasState, was .very pure in nature and suitable for use as a standard sand. The thoroughly washed sandpassing S50-micron IS Sieve and r etained on 600micron IS Sieve was observed to satisfy the require-ments of standard sand as a substitute for the imported sand. Accordingly, the Sectional Committeeformulated IS 650 : 1955 which recommended Ennore sand passing S50-micron IS Sieve and not morethan 10 percent by mass passing 600-micron IS Sieve. This grading was the same as that for Leighton-Buzzard sand:

In the light of experience gained with the practical use of Indian Standard sand (conforming toIS 650 ~ 1955) for testing the compressive and tensile strength of Indian cement over the period,certain drawbacks " ~bserved in respect of compressive and tensile strength values. the quantityof gauging water altd the reproducibility of results. The Sectional Committee was of the view thatthese drawbacks could be overcome by revising the grading of Ennore sand. On the recommendationsof the Sectional Committee, the Council of Scientific and Industrial Research sponsored the schemeof investigations on 'Mortar making properties of Ennore sand' to be carried out at the Concrete andSoil Research Laboratory, Madras under the guidance of the then lSI with the following mainobjects:

a) To determine the optimum grading of Ennore sand which would give the highest strengthkeeping at the same time, the yield from the quarry as high as possible; and

b) To introduce one or more intermediate size requirement in the grading specification with aview to controlling uniformity of grading and thus to ensure better reproducibihty ofresults.

As a result of the above investigations, and on the recommendations of the Concrete and SoilResearch Laboratory, Madras, the Sectional Committee decided to revise the grading ofEnnore sandto make it more suitable from the technical and exploitation point of view and also to bring it in linewith the RILEM CEMBUREAU grading of sand for testing of cement recommended by the Interna-tionalOrganization for Standardization (ISO). First revision of the standard was printed in 1966mainly with a view to incorporating the revised grading of standard sand.'

The Sectional Committee records its deep appreciation to all those who have assisted in the impor-tant investigations related to regrading of the standard sand and in particular to the Concrete andSoil Research Laboratory, Madras;' the Central Roa.d R~search Institute, ~ew Delhi; EngineeringResearch Laboratory, Hyderabad; Maharashtra Engineer ing Research InstItute Nasik: and thelaboratories of various cement factories in the country.

This revision has been taken up with a view to incorporating various amendments issued to thisstandard from time to time in view of changes required in clauses on source of standard sand, pack-ing and marking.For the purpose of deciding whether a particular requirement of this standard is complied with, thefinal value, observed or calculated, expressing the result of a test or analysis, shall be rounded off inaccordance with IS 2 : 1960 'Rules for rounding off numerical values i revised Y, The number of signi-ficant places retained in the rounded off value should be the same as that of the specified value in thisstandard.

Indian StandardSTANDARD SAND FOR TESTING CEMENT-

SPECIFICATION( Second Revision)

1 SCOPEThis standard lays down requir ements for Stan-dard sand used in testing of cement.

2 REFERENCESThe Indian Standards listed below are neces-sary adjuncts to this standard:

.3 SOURCE'the standard sand shall be obtained fromEnnore Tamil Nadu. Particle size greater than1 mru of the Standard sand may also be obtain-cd from Mudaliarkuppam, Tamil Nadu (seeNote ).

NOTE - Supplies of the standard sand may beobtained from Tamil Nadu Minerals Ltd. 31, Kama-rajar Salai, TWAD Board Buildings, Chepauk,M:ldras 600005.

4 PHYSICAL CHARACTERISITICS4.1 The standard sand shall be of quartz, lightgrey or whitish variety and shall be free fromsilt. The sand grains shall be angular, the shapeof the grains approximating to the sphericalform; elongated and flattened grains being pre-sent only in very small or negligible ,quantities.4.2 The standard sa nd shall (100 percent)pass through 2-ml11 IS sieve and shall be ( 100percent ) retained \.11\ 90-micron IS Sieve withthe following particle size distribution:

Particle Si:e PercentSmaller than 2 mrn and g rea- 33'33

Particle Size PercentSmaller than 1 mm and greater 33'33

than 500 micronsBelow 500 microns but greater 33'33
