Designation: C1157/C1157M − 17Standard Performance Specif i cation forHydraulic Cement 1This standard is issued under the f i xed designation C1157/C1157M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This performance specif i cation covers hydraulic ce-ments for both general and special applications. There are norestrictions on the composition of the cement or its constituents(See Note 1).N OTE 1—There are two related hydraulic cement standards, Specif i ca-tion C150 for portland cement and Specif i cations C595 for blendedcements, both of which contain prescriptive and performance require-ments1.2 This performance specif i cation classif i es cements basedon specif i c requirements for general use, high early strength,resistance to attack by sulfates, and heat of hydration. Optionalrequirements are provided for the property of low reactivitywith alkali-silica-reactive aggregates and for air-entrainingcements.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard. Values in SI units [or inch-pound units] shallbe obtained by measurement in SI units [or inch-pound units]or by appropriate conversion, using the Rules for Conversionand Rounding given in IEEE/ASTM SI 10, of measurementsmade in other units [or SI units]. Values are stated in only SIunits when inch-pound units are not used in practice.1.4 The text of this standard refers to notes and footnotesthat provide explanatory material. These notes and footnotes(excluding those in tables and f i gures) are not requirements ofthe standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.
