18、ing strength development, sulfateresistance, heat of hydration, and resistance to alkali-silica reactivity.Concrete performance is dependent on many factors such as characteris-tics of other concrete materials, mix design, production, handling, andenvironmental conditions. For performance properties

19、 of concrete, includ-ing permeability, resistance to freeze-thaw cycles and deicer salt scaling,additional information may be obtained through the use of comparativetesting of concretes.4.2 Cements conforming to this specification shall be des-ignated in accordance with the nomenclature with special

46、 Testing by the Manufacturer11.1 Test samples of cement for compliance with thisspecification, and for chemical analysis, air content, andfineness. Location and frequency of sampling are at thediscretion of the manufacturer and are permitted to be changedupon agreement between the purchaser and supp
