DIN EN 12188 PDF Download

The DIN EN 12188 standard provides test methods for the evaluation of structural bonding agents used in the protection and repair of concrete structures. The main focus of this standard is on the characterization of the adhesion between steel plates, which are commonly used for reinforcing concrete structures.

The standard includes two specific test methods: slant shear strength and pull-off strength. The slant shear strength test evaluates the bonding agent's ability to resist horizontal shearing forces. This test involves applying a constant load to a slanted steel plate bonded to another steel plate with the bonding agent and measuring the force required to cause failure.

The pull-off strength test assesses the bonding agent's ability to resist vertical forces. In this test, a steel plate is bonded to a concrete substrate using the bonding agent, and a vertical force is applied to pull the plate away from the concrete. The force required to achieve failure is measured, providing an indication of the bonding agent's performance.

By defining these test methods, the standard ensures that structural bonding agents meet specific criteria for strength, durability, and reliability. Compliance with DIN EN 12188 enables manufacturers, contractors, and users of concrete repair materials to have confidence in the quality and performance of the products they are using.
