Products and Systems for the Protection and Repair of Concrete Structures - Test Methods - Determination of Open Time
Also Known As:
The DIN EN 12189 standard provides a specific test method for determining the open time of products and systems used for protecting and repairing concrete structures. The open time refers to the amount of time during which a bonding agent remains workable after application, before it dries or hardens.
To conduct the test, bonded concrete prisms are subjected to flexure, which involves applying a force to measure the bonding agent's ability to maintain its integrity under stress. The open time is measured by determining the moment at which failure occurs and comparing it to the time of application.
This standard is important for ensuring the quality and effectiveness of bonding agents used in concrete structures. By defining a standardized test method, it allows manufacturers, contractors, and users to evaluate and compare different products and systems based on their open time performance. This information is crucial for selecting the most suitable products for protecting and repairing concrete structures, as well as for determining proper application techniques and limitations.
