This Indian Standard (Part IV) was adopted by the Indian Standards Institution on 24 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 concrete is the quality of aggregates used therein. The test methods given in this standard are intended to assist in assessing the quality of aggregates. In a given situation, for a particular aggregate, it may not be necessary to assess all the qualities and 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 be 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 following eight parts of Indian Standard Methods of Test for Aggregates for Concrete (IS : 2386-1963) :
Part I Particle Size and Shape
Part II Estimation of Deleterious Materials and Organic Impurities
Part III Specific Gravity, Density, Voids, Absorption and Bulking
Part IV Mechanical Properties
Part V Soundness
Part VI Measuring Mortar Making Properties of Fine Aggregate
Part VII Alkali Aggregate Reactivity
Part VIII Petrographic Examination
The Sectional Committee responsible for the preparation of this standard has taken into consideration the views of concrete specialists, testing authorities, consumers and technologists and has related the standard to the practices followed in this country. Further, the need for international co-ordination among standards prevailing in different countries of the world has also been recognized. These considerations led the Sectional Committee to derive assistance from the published standards and publications of thy following organizations: British Standards Institution American Society for Testing and Materials Wherever a reference to any Indian Standard appears in these methods, 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 : Z-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.
