Products and Systems for the Protection and Repair of Concrete Structures - Test Methods - Determination of Injectability and Splitting Test
Also Known As:
The DIN EN 1771 standard provides a method for evaluating the injectability and adhesion of products used for protecting and repairing concrete structures. The standard focuses on determining the ability of a product to be injected into a capillary network within the concrete, as well as its ability to adhere to the concrete surface.
The injectability measurement is carried out by injecting the product into a cylindrical mortar sample that has been prepared with a capillary network resembling that of concrete. The injectability is assessed by measuring the splitting strength of the mortar samples after injection. This test method allows for evaluating the product's ability to penetrate the capillaries and effectively fill voids, ensuring proper protection and repair of concrete structures.
By determining the injectability and adhesion of these products, the standard aims to provide a reliable and standardized method for assessing their performance. This enables manufacturers, contractors, and end-users to select and use products that meet the required criteria for protecting and repairing concrete structures effectively.
