ASTM C465-09 - 15.5.2009
 
1. Scope

1.1 This specification pertains to the criteria and tests to be used for determining whether a(n) organic or inorganic processing addition, when used in the recommended amount at the option of the cement producer in the manufacture of hydraulic cements, meets the requirements as prescribed by definition in Specifications C 150, C 1157, C 845, and C 595. The materials listed in the following former ASTM Specifications shall be considered as meeting the organic processing additions requirements of this specification:

C 150 – 62, for Portland Cement

C 205 – 58 T, for Portland Blast-Furnace Slag Cement

C 340 – 58 T, for Portland Pozzolan Cement

C 358 – 58, for Slag Cement

1.2 The following safety hazards caveat pertains only to the test methods described in this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
