Standard Test Method for

Sieve Analysis of Fine and Coarse Aggregates1
This standard is issued under the fixed designation C 136; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e)indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.

1. Scope* 1.1 This test method covers the determination of the particle size distribution of fine and coarse aggregates by sieving. 1.2 Some specifications for aggregates which reference this method contain grading requirements including both coarse andfine fractions. Instructions are included for sieve analysis of such aggregates. 1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information purposes only. Specification E 11 designates the size of sieve frames with inch units as standard, but in this test method the frame size is designated in SI units exactly equivalent to the inchunits. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2.

E 11 Specification for Wire-Cloth and Sieves for Testing Purposes 2.2 AASHTO Standard: AASHTO No. T 27 Sieve Analysis of Fine and Coarse Aggregates3 3. Terminology 3.1 Definitions—For definitions of terms used in this standard, refer toTerminology C 125. 4. Summary of Test Method 4.1 A sample of dry aggregate of known mass is separated through a series of sieves of progressively smaller openings for determination of particle size distribution. 5. Significance and Use 5.1 This test method is used primarily to determine the grading of materials proposed for use as aggregates or being used as aggregates. The results are used todetermine compliance of the particle size distribution with applicable specification requirements and to provide necessary data for control of the production of various aggregate products and mixtures containing aggregates. The data may also be useful in developing relationships concerning porosity and packing. 5.2 Accurate determination of material finer than the 75-µm (No. 200) sieve cannot be achievedby use of this method alone. Test Method C 117 for material finer than 75-µm sieve by washing should be employed. 5.3 Refer to methods of sampling and testing in Specification C 637 for heavyweight aggregates. 6. Apparatus 6.1 Balances—Balances or scales used in testing fine and coarse aggregate shall have readability and accuracy as follows: 6.1.1 For fine aggregate, readable to 0.1 g and accurate...
