In the case of coarse / fine aggregate mixtures, the minus 4.75 mm (No. 4) may be distributed among two or more sets of sieves to prevent overloading of individual sieves.

Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings. ... Some specifications may require more ...
Fine aggregate failing to meet the sieve analysis and fineness modulus requirements of Sections 5.1, 5.2, or 5.3, may be accepted provided that concrete made with similar fine aggregate from the same source has an acceptable performance record in similar concrete construction; or, in the absence of a demonstrable service record, provided that ...
The fine aggregate angularity (FAA) test (Figure 1) is an indirect method of assessing the angularity of fine aggregate. Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the …

aggregate through successively smaller sieves and measuring the weight retained on each sieve. Fine content (-#200 sieve or smaller than ~0.003 inches) is determined by washing the aggregate to separate this fine material from the larger pieces.
