ASTM C1857

Full Name

ASTM C1857 – Standard Test Method for Evaluating the Adhesion (Pull-Off) Strength of Concrete Repair and Overlay Mortar


This test method is suitable for laboratory use to determine one or more of the following:

  1. The bond strength of a repair or an overlay material to a specific concrete substrate.
  2. The tensile strength of a repair or overlay material after the material has been applied to the concrete substrate.
  3. The change in bond strength when applying a bonding agent or other bond modifying treatment to the concrete substrate.
