ASTM C1583-13: Tensile Strength of Concrete Surfaces and the Bond Strength
Standard: ASTM C1583-13 – Standard Test Method for Tensile Strength of Concrete Surfaces and the Bond Strength or Tensile Strength of Concrete Repair and Overlay Materials by Direct Tension (Pull-off Method)
Scope: ASTM C1583 is used to determine the following:
- The near-surface tensile strength of the substrate as an indicator of the adequacy of the surface preparation before application of a repair or overlay material.
- The bond strength of a repair or an overlay material to the substrate.
- The tensile strength of a repair or overlay material, or an adhesive used in repairs, after the material has been applied to a surface.
Applicable Products: This test method is performed on the surface of a prepared concrete base before application of a concrete repair or overlay material, or on the surface of a concrete repair or overlay material after the material has been applied to the prepared concrete surface.
Test Procedure: The test specimen is formed via drilling a shallow core into and perpendicular to the surface of the substrate, and leaving the intact core attached to the concrete. A steel disk is bonded to the top surface of the test specimen. A tensile load is applied to the steel disk until failure occurs. The failure load and the failure mode are recorded and the nominal tensile stress at failure is calculated.
End Result: Upon the completion of a successful test, the concrete surface, repair or overlay meets the performance criteria for water penetration resistance or does not meet criteria and further remediation may be required to pass.
