Attachment of stone units is accomplished by either mechanical anchorage or adhesive bonding, or in some situations a hybrid system using both methodologies. Test methods exist to proof both mechanical and adhesive systems. Given the vast variety of products and designs available to accomplish attachment, the test methods tend to be less standardized than physical property testing methods to allow for customization of the method per the specific parameters of the project components. This session will uncover the mysteries of the ASTM C1354 (Individual Stone Anchorages), ASTM C1201 (Full Panel Stone), and the newly published ASTM C1823 (Shear Bond of Adhered Stone) test methods. Attention will be focused on how the methods are customized to address specific and unique situations.  

Learning Objectives:

• Understand the primary factors influencing the selection of mechanical anchors versus adhesive attachment, and how to incorporate this knowledge into your project.
• Develop an awareness of the flexibilities intentionally written into the ASTM anchorage test procedures and how this allows for customization that fits project components.
• Learn why shear values govern adhesive proof testing rather than tensile, addressing specific and unique situations that may arise.
• Get clarification of directional and bidirectional load paths in the fixturing of anchor tests.
