General Characteristics
9、3.1 Aggregates shall consist of natural sand or manufac-tured sand, used alone or in combination with coarse aggregateas described in this specification. Manufactured sand is theproduct obtained by crushing stone, gravel, or air-cooled ironblast-furnace slag. Coarse aggregate shall consist of crushe
10、dstone, gravel, or air-cooled iron blast-furnace slag processed toassure suitable gradation.NOTE 1Care should be taken to ensure a suitable particle shape, sinceexcessive quantities of flat and elongated particles have historically causedproblems with workability.4. Grading4.1 Grading shall conform
11、to the requirements in Table 1 orshall comply with the requirements of 4.2.NOTE 2Size No. 1 is that specified for concrete sand in SpecificationC33; Size No. 2 is that specified for masonry mortar in SpecificationC144; and Sizes 8 and 89 are standard sizes as given in Specification C33.4.2 Aggregate
12、s of gradations other than those covered byTable 1 are permitted if all of the requirements of 4.2.1, 4.2.2,and 4.2.3 are met.4.2.1 One hundred percent of the fine aggregate shall passthe 9.5mm(38-in.) sieve and no more than 5 % natural sand or10 % for manufactured sand shall pass the 75- mm (No. 20
13、0)sieve.4.2.2 One hundred percent of the coarse aggregate shall passthe 12.5-mm (12-in.) sieve and no more than 5 % shall pass the600-m (No. 30) sieve.4.2.3 The compressive strength of grout shall be specifiedand meet the requirements of Specification C476.1This specification is under the jurisdicti

17、 Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.15. Deleterious Substances5.1 The amounts of deleterious substances in either fine orcoarse aggregate shall not exceed the following:PermissibleContent, max,Deleterious Substances weight %Friable part
18、icles 1.0Lightweight particles, floating on liquid 0.5Ahaving a specific gravity of 2.0AThis requirement does not apply to blast-furnace slag aggregate.6. Organic Impurities6.1 The fine aggregate shall be free from injurious amountsof organic impurities. Except as herein provided, aggregatessubjecte
19、d to the test for organic impurities and producing acolor darker than the standard shall be rejected.6.2 Fine aggregate failing in the test may be used, providedthat the discoloration is due principally to the presence of smallquantities of coal, lignite, or similar discrete particles.6.3 A fine agg
20、regate failing in the test may be used,provided that, when tested for the effect of organic impuritieson strength of mortar, the relative strength at 7 days calculatedin accordance with Section 11 of Test Method C87 is not lessthan 95 %.7. Soundness7.1 Except as herein provided, either fine or coars
21、e aggre-gates subjected to 5 cycles of the soundness test shall show aloss, weighted in accordance with the grading of a samplecomplying with the limitations prescribed in Section 4, notgreater than 10 % when sodium sulfate is used or 15 % whenmagnesium sulfate is used.7.2 Aggregate failing to meet
22、the requirements of 7.1 maybe accepted, provided that grout of comparable propertiesmade from similar aggregate from the same source has beenexposed to weathering, similar to that to be encountered, for aperiod of more than 5 years without appreciable disintegration.8.
