GSO ASTM C1157/C1157M:2024 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.
