18、 5 % natural sand or 10 %for manufactured sand shall pass the 75- mm (No. 200) sieve.5.2.2 One hundred percent of the coarse aggregate shall pass the 12.5-mm (12-in.) sieve and no more than 5 % shall pass the600-m (No. 30) sieve.5.2.3 The compressive strength of grout shall be specified and meet the
19、 requirements of Specification C476.6. Deleterious Substances6.1 The amounts of deleterious substances in either fine or coarse aggregate shall not exceed the following:PermissibleContent, max,Deleterious Substances weight %Friable particles 1.0Lightweight particles, floating on liquid 0.5Ahaving a
20、specific gravity of 2.0A This requirement does not apply to blast-furnace slag aggregate.7. Organic Impurities7.1 The fine aggregate shall be free from injurious amounts of organic impurities. Except as herein provided, aggregatessubjected to the test for organic impurities and producing a color dar
21、ker than the standard shall be rejected.7.2 Fine aggregate failing in the test may be used, provided that the discoloration is due principally to the presence of smallquantities of coal, lignite, or similar discrete particles.7.3 A fine aggregate failing in the test may be used, provided that, when
22、tested for the effect of organic impurities on strengthof mortar, the relative strength at 7 days calculated in accordance with Section 11 of Test Method C87C87/C87M is not less than95 %.8. Soundness8.1 Except as herein provided, either fine or coarse aggregates subjected to 5 cycles of the soundnes
23、s test shall show a loss,weighted in accordance with the grading of a sample complying with the limitations prescribed in Section 45, not greater than 10 %when sodium sulfate is used or 15 % when magnesium sulfate is used.8.2 Aggregate failing to meet the requirements of 7.18.1 may be accepted, prov
