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.
1.2 The values stated, in either SI units or other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore each system must be used independently of the other, without combining values in any way.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
