Standard Test Method for Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50 mm] Cube Specimens)
Published by ASTM International, 07/15/2021
ASTM C109/C109M, 2021 Edition – Standard Test Method for Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50 mm] Cube Specimens)
This test method covers determination of the compressive strength of hydraulic cement mortars, using 2-in. or [50 mm] cube specimens.
NOTE 1—Test Method C349 provides an alternative procedure for this determination (not to be used for acceptance tests).
This test method covers the application of the test using either inch-pound or SI units. The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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 nonconformance with the standard.
Values in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI-10, of measurements made in other units.
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. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)
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.

04.01: Cement; Lime; Gypsum
Volume 04.01 features specifications and test methods that establish the property requirements and measurement procedures for hydraulic cements, including portland, natural, pozzolanic, masonry, rapid hardening, and slag.
It includes standards that define the appropriate qualities of lime and limestone and how to analyze them for environmental and industrial uses.
The remaining standards in this volume address gypsum and related building materials and systems, including application procedures and related accessories, including exterior insulation and finishing systems (EIFS).
ASTM’s Manual of Cement Testing, a valuable companion to these standards, also appears in this volume.
