ASTM C1157/C1157M-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: C1157/C1157M − 20a C1157/C1157M − 23
Standard Performance Specification for
Hydraulic Cement
This standard is issued under the fixed designation C1157/C1157M; the number immediately following the designation indicates the year
of 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 specification covers hydraulic cements for both general and special applications. There are no restrictions
on the composition of the cement or its constituents (see Note 1).
NOTE 1—There are two related hydraulic cement standards, Specification C150/C150M for portland cement and Specifications C595/C595M for blended
cements, both of which contain prescriptive and performance requirements
1.2 This performance specification classifies cements based on specific requirements for general use, high early strength,
resistance to attack by sulfates, and heat of hydration. Optional requirements are provided for the property of low reactivity with
alkali-silica-reactive aggregates and for air-entraining cements.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in non-conformance with the standard. Values in SI units [or inch-pound units] shall be obtained by
measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given
in IEEE/ASTM SI 10, of measurements made in other units [or SI units]. Values are stated in only SI units when inch-pound units
are not used in practice.
1.4 The text of this performance specification refers to notes and footnotes that provide explanatory material. These notes and
footnotes (excluding those in tables and figures) are not requirements of the standard.
1.5 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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions:
3.1.1 Terms used in this specification are defined in Terminology C219.
4. Classification and Use
4.1 The types of hydraulic cement covered by this specification are given in 4.2.1 – 4.2.6 and are classified in accordance with
specific properties defined in Table 1 (see Note 2).
NOTE 2—This specification is based on hydraulic cement attributes related to concrete performance, including strength development, sulfate resistance,
heat of hydration, and resistance to alkali-silica reactivity. Concrete performance is dependent on many factors such as characteristics of other concrete
materials, mix design, production, handling, and environmental conditions. For performance properties of concrete, including permeability, resistance to
freeze-thaw cycles and deicer salt scaling, additional information may be obtained through the use of comparative testing of concretes.
4.2 Cements conforming to this specification shall be designated in accordance with the nomenclature with special characteristics
indicated by type in accordance with the types in 4.2.1 – 4.2.6. When the type is not specified, the requirements of type GU shall
apply.
4.2.1 Type GU—Hydraulic cement for general construction. Use when one or more of the special types are not required.
4.2.2 Type HE—High Early-Strength.
4.2.3 Type MS—Moderate Sulfate Resistance.
4.2.4 Type HS—High Sulfate Resistance.
4.2.5 Type MH—Moderate Heat of Hydration.
4.2.6 Type LH—Low Heat of Hydration.
4.3 Additional Options—The following additional purchase options apply for any of the principal types listed. When one or both
of these options is invoked, its letter designation and title shall follow immediately after the respective letter designation and title
of the principal type (for example, Type MS(R) or Type MS(A)).

estimates based on historical production data. The report shall indicate if such estimates are provided.
