BS EN 13581:2002

This standard BS EN 13581:2002 Products and systems for the protection and repair of concrete structures. Test methods. Determination of loss of mass of hydrophobic impregnated concrete after freeze-thaw salt stress is classified in these ICS categories:

• 91.080.40 Concrete structures
• 91.100.30 Concrete and concrete products

This European Standard is one of a series dealing with products and systems for the protection and repair of concrete structures. It specifies a method for determining the loss of mass after freeze-thaw salt stress in sodium chloride solution. It can be used to test the resistance of hydrophobic impregnated concrete as well as the untreated concrete. There are two types of concrete deterioration when a freeze-thaw attack occurs: surface scaling and internal damage.
