  • MASONRY MORTAR TESTING - NCMA

    Compressive Strength Testing of Field-Prepared Mortar. Compressive strength is one of the most commonly tested properties of field mortar. The test, described in ASTM C780, provides an indication of mortar consistency during construction, not as an indication of the compressive strength of the masonry, or even of the mortar in the wall. Compressive strength test results should be compared on a ...

  • When should mortar cube testing be performed?

    ANSWER: Mortar is typically specified to meet the “proportion specification”, which is the default in ASTM C270. The only circumstance in which mortar cube testing is required is when the mortar has been specified by the “property specification” and the proposed mix design must be verified to meet the property requirements of ASTM C270.
