ASTM C1404 – Standard Test Method for Bond Strength of Adhesive Systems Used with Concrete as Measured by Direct Tension (Withdrawn 2010)
Description:
Significance and Use
The bonding properties of adhesives are important for concrete repair applications. This test method provides a means to measure the adhesive characteristics of materials used to bond freshly mixed mortar to hardened concrete.
In addition to providing information on bond strength, the location of failure is determined visually and is thus instructive regarding the weakest element in the composite tested.
The bond strength that is measured is limited by the tensile strength of the base concrete and mortar. While an attempt has been made to choose materials that are strong enough to force a bond failure, there may be cases where failure occurs in concrete or mortar. In these situations, the actual bond strength exceeds the measured result.
Scope
1.1 This test method covers the laboratory determination of the bond strength of adhesive systems used to adhere freshly mixed mortar to hardened portland-cement concrete.
