This Indian Standard ( Part VI ) was adopted by the Indian Standards Institution on 13 September 1963, after the draft finalized by the Cement and Concrete Sectional Committee had been approved by the Building Division Council. One of the major contributing factors to the quality of corlcrete is the qualitv of aggregates used therein. The test methods given in this standard are intended to assist in assessing the quality of aggregates. In iI given situation, for a particular aggregate, it ma)’ r.ot be necessary to pssess all the qualities ancl therefore it is necessary to determine beforehand the purpose for which a concrete is being used and the qualities of the aggregate which require to he assessed. Accordingly, the relevant test methods may be chosen from amongst the various tests covered in this standard. For the convenience of the users. the test methods are grouped into the fol!owing eight parts of Indian Standard Methods of Test for .4ggregates for Concrete ( IS : 2386 – 1963 ):
Part I Particle Size and Shape
Part II Estimation of Deleterious hlaterials and Organic Impurities
Part III Specific Gravity, Density, J’oids, Absorption and Bulking
Part IV Mechanical Properties
Part V Soundness _
Part VI lfeasrlring Mortar Making Properties of Fine Aggregate
Part VII ;\lkali Aggregate Reactivit!
Part VIII l’etrographir Examination
The Sectional Committee responsible for the prrpa~ation of this standard has taken into consideration the views of the concrete specialists, testing authorities, consun~crs and technologists and has relnlrd the standard to the practices followed in this country. Further, the l:crd for international co-ordination among standards prex.ailing in differ-cnt countries of the world has also been recognized. These considerations led the Sectional Committee to derive assistance from C 87.- 62T Tentative Method of Test for Measuring Mortar Making Properties of Fine Aggregate issued by American Society for Testing and Materials. Wherever a reference to any Indian Standard appears in this method, it shall be taken as a reference to its latest version. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2 – 1960 Rules for Rounding Off Numerical Values ( Revised). The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. This standard is intended chiefly to cover the technical provisions relating to testing of aggregates for concrete, and it does not include all the necessary provisions of a contract.
