Standard Specification for Processing Additions for Use in the Manufacture of Hydraulic Cements
ABSTRACT
This specification covers the criteria and tests to be used for determining whether a processing addition meets the requirement. When proposed addition is accepted for general use in Portland cement, tests shall be made on cements prepared from at least five different clinkers. These clinkers shall represent two Type I cements, one Type II cement, and two Type III cements. Processing additions shall be evaluated by comparing cements containing the addition to otherwise identical cements from the same source without the addition, or containing a processing addition. The compressive strength and flexural strength of the concrete made with cement containing the addition shall be compared with strengths obtained with the control cement at similar ages. The properties of the materials shall be determined through the following tests in accordance with the following standard: chemical analysis of the cement, compound composition, fineness of cement, normal consistency, time of setting, autoclave expansion, air content of mortar, compressive strength of mortar, and drying shrinkage of mortar.
SCOPE
1.1 This specification pertains to the criteria and tests to be used for determining whether a 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 requirements of this specification: C 150 - 62, for Portland CementC 205 - 58 T, for Portland Blast-Furnace Slag CementC 340 - 58 T, for Portland Pozzolan CementC 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.
