ASTM C33/C33M-13 pdf free.Standard Specification for Concrete Aggregates.
ASTM C33/C33M defines the requirements for grading and quality of fine and coarse aggregate (other than lightweight or heavyweight aggregate) for use in concrete.
8. Soundness
8.1 Except as provided in 8.2 and 8.3, tine aggregate subjected to five cycles of the soundness test shall have a weighted average loss not greater than 10 % when sodium sulfate is used or 15 % when magnesium sulfate is used.
8.2 Fine aggregate failing to meet the requirements of 8.1 shall be regarded as meeting the requirements of this section provided that the supplier demonstrates to the purchaser or spccificr that concrete of comparable properties. made from similar aggregate from the same source, has given satisfactory service when exposed to weathering similar to that to he encountered.
8.3 Fine aggregate not having a demonstrable service record and failing to meet the requirements of 8.1 shall be regarded as meeting the requirements of this section provided that the supplier demonstrates to the purchaser or specifier it gives satisfactory results in concrete subjected to freezing and thawing tests (see Test Method C666/C666M).
10. Grading
10.1 Coarse aggregates shall conform to the requirements prescribed in Table 3 for the size number specified.
Nom s—The ranges shown in Table 3 arc by necessity very wide in order to acconNilodate nationwide condnions. For quality control of any specific operation, a producer should develop an average grading for the particular source and production facilities, and should control the production gradings within reasonable tolerances from this average. Where coarse aggregate size numbers 357 or 467 are used, the aggregate should be furnished in at least two separate sizes.
11. Deleterious Substances
11 .1 Except for the provisions of 11 .3, the limits given in Table 4 shall apply for the class of coarse aggregate designated in the purchase order or other document (see Note 9 and Note 10). If the class is not specified, the requirements for Class 3S, 3M, or I N shall apply in the severe, moderate, and negligible weathering regions, respectively (see Table 4 and Fig. 1).
