Products and Systems for the Protection and Repair of Concrete Structures - Test Method - Determination of Loss of Mass of Hydrophobic Impregnated Concrete after Freeze-Thaw Salt Stress
Also Known As:
This standard, DIN EN 13581, focuses on the protection and repair of concrete structures. It specifically addresses the determination of the loss of mass of hydrophobic impregnated concrete after exposure to freeze-thaw salt stress. The objective of this test method is to assess the resistance of both untreated concrete and concrete treated with hydrophobic impregnation.
The standard involves subjecting the concrete specimens to a solution of sodium chloride and subjecting them to a freeze-thaw cycle. This cycle mimics the natural conditions that concrete structures may face in regions with cold climates or areas that use de-icing salts. The test determines the mass loss of the concrete after the exposure, which can indicate the level of durability and resistance to freeze-thaw attack.
Concrete deterioration due to freeze-thaw attack can occur in two ways: surface scaling and internal damage. Surface scaling refers to the flaking or spalling of the concrete surface, while internal damage refers to the cracking and deterioration within the concrete matrix. The test method provided in this standard helps assess the potential for these types of deterioration and can be used to evaluate the performance of concrete products and systems for protection and repair.
