ASTM C109-C109M STANDARD TEST METHOD FOR COMPRESSIVE STRENGTH OF HYDRAULIC CEMENT MORTARS (USING 2-IN. OR [50-MM] CUBE SPECIMENS)
Revision Edition 08 Chg: Date: 12/01/08 ASTM C109-C109M
This ASTM C109-C109M test method covers determination of the compressive strength of hydraulic cement mortars, using 2-in. or [50-mm] cube specimens.
NOTE 1: Test Method C 349 provides an alternative procedure for this determination (not to be used for acceptance tests).
This ASTM C109-C109M 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 Standard IEEE/ASTM SI 10, of measurements made in other units.
This ASTM C109-C109M 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. (Warning: Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)
