Products and systems for the protection and repair of concrete structures - Test methods - Part 3: Determination of the adhesion of injection products, with or without thermal cycling - Slant shear method
Also Known As:
DIN EN 12618-3 standard specifies the test method for determining the adhesion of injection products used for the protection and repair of concrete structures. The specific focus of this standard is on the slant shear method for measuring bond strength.
The standard applies to all injection products that aim to restore cracked concrete, as covered by prEN 1504-5. The test can be conducted on cracks that are in a dry, damp, wet, or water-flowing state. The test should be performed after the appropriate curing period under standardized conditions. Additionally, a further set of specimens can undergo a period of artificial ageing via thermal cycling before testing.
The typical method for testing the repaired crack is through short-term static load. However, the standard also allows for alternative testing methods such as long-term static load or dynamic load cyclic tests. These optional tests provide additional flexibility for evaluating the performance of the injection products under different loading conditions.
