Scope*1.1 This specification defines the requirements for grading and quality of fine and coarse aggregate (other than lightweight orheavyweight aggregate)
3、 for use in concrete.21.2 This specification is for use by a contractor, concrete supplier, or other purchaser as part of the purchase documentdescribing the material to be furnished.NOTE 1This specification is regarded as adequate to ensure satisfactory materials for most concrete. It is recognized
4、 that, for certain work or in certainregions, it may be either more or less restrictive than needed. For example, where aesthetics are important, more restrictive limits may be consideredregarding impurities that would stain the concrete surface. The specifier should ascertain that aggregates specif
5、ied are or can be made available in thearea of the work, with regard to grading, physical, or chemical properties, or combination thereof.1.3 This specification is also for use in project specifications to define the quality of aggregate, the nominal maximum size ofthe aggregate, and other specific
6、grading requirements. Those responsible for selecting the proportions for the concrete mixtureshall have the responsibility of determining the proportions of fine and coarse aggregate and the addition of blending aggregatesizes if required or approved.1.4 The values stated in either SI units or inch
7、-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.5 The text of this standard re

Grading6.1 Sieve AnalysisFine aggregate, except as provided in 6.2 and 6.3 shall be graded within the limits in Table 1.NOTE 3Concrete with fine aggregate gradings near the minimums for percent passing the 300 m (No.50) and 150 m (No.100) sometimes havedifficulties w

The addition of entrained air, additional cement, or the addition of an approved mineraladmixture to supply the deficient fines, are methods used to alleviate such difficulties.6.2 The fine aggregate shall have not more than 45 % passing any sieve and
46、retained on the next consecutive sieve of thoseshown in 6.1, and its fineness modulus shall be not less than 2.3 nor more than 3.1.6.3 Fine aggregate failing to meet these grading requirements shall meet the requirements of this section provided that thesupplier can demonstrate to the purchaser or s

48、ceptable performance record in similarconcrete construction.NOTE 4Manufactured fine aggregate having elevated proportions of material passing the 75-m (No. 200) sieve may need further evaluation to ensurethat material passing the 75-m (No. 200) sieve is essentially composed of dust of fracture deriv
49、ed from the parent rock in the crushing operation, anddoes not contain an appreciable level of clay minerals or other deleterious constituents as described in Descriptive Nomenclature C294. Because someof the dust of fracture may occur in the clay size range, defined here as material finer than 2 m, care must be taken to properly differentiate theseclay-sized materials from clay minerals. Natural fine aggregate with elevated proportions of material passing the 75-m (No. 200) sieve may have higherpotential for clay mineral content.Various means are
