    (Drying Shrinkage).

    General Information on ASTM Specifications for Masonry Assemblages

    ASTM specifications for standard methods of test for masonry assemblages are summarized below:
    • ASTM E72: Strength Tests of Panels for Building Construction (lateral load by air bag)
    • ASTM E514: Water Permeance of Masonry
    • ASTM E518: Flexural Bond Strength of Masonry (modulus of rupture)
    • ASTM E519: Diagonal Tension (Shear) in Masonry Assemblages
    • ASTM C1072: Measurement of Masonry Flexural Bond Strength  (bond wrench)
    • ASTM C1314: Measurement of Compressive Strength of Masonry Prisms to Determine Compliance with fm′
    • ASTM C1357: Evaluating Masonry Bond Strength

    Concluding Remarks on ASTM Specifications for Masonry

    The above apparently bewildering list of applicable ASTM specifications covers almost every possible aspect of masonry mortar, units, and assemblages. While the ASTM specifications can help organize the field, they may have indirect rather than direct relationships with the performance of the finished masonry. To shed more light on this point, we must investigate the desired performance characteristics of masonry materials, and study the relation between those characteristics and the ASTM specifications.
