This test method covers determination of the compressive strength of hydraulic cement mortar,using 50-mm (or 2-in.) cube specimens.
Note 1–ASTM C 349 provides an alternative procedure for this determination (not to be usedfor acceptance tests).
This test method covers the application of the test using either inch-pound or SI units. The valuesstated in either system shall be regarded separately as standard. Within the text, the inch-poundunits are shown in brackets. The values stated in each system are not exact equivalents; therefore,each system shall be used independently of the other. Combining values from the two systemsmay result in nonconformance with the specification.
Values in SI units shall be obtained by measurement in SI units or by appropriate conversion,using the Rules for Conversion and Rebounding given in Standard IEEE/ASTM SI 10, ofmeasurements made in other units.
