CEN/TC 104/SC 8/WG 1 - Surface protection systems

This Part of prEN 1504 specifies requirements for the identification, performance (including durability aspects), safety and evaluation of conformity of products and systems to be used for surface protection of concrete, to increase the durability of concrete and reinforced concrete structures, as well as for new concrete and for maintenance and repair work.
The surface protective methods covered by this standard are the following:
-   hydrophobic impregnation;
-   impregnation;
-   coating.
Flooring systems in buildings which are not intended to protect or reinstate the integrity of a concrete structure are standardised in EN 13813.
When products and systems complying with this standard are used in flooring applications that involve substantial mechanical loading , they should also satisfy the requirements of EN 13813.

This European Standard specifies a method for determining the resistance to chloride ion penetration of hardened CC or PCC repair products and systems for the protection and repair of concrete, as defined in prEN 1504-3.
The provisions of the standard are applicable to cementitious grouts, mortars and concretes with a maximum aggregate size of 20 mm.

This European Standard specifies a method for determining the resistance to severe chemical attack of surface protection systems.

This European Standard specifies a method for determining the thixotropy of products and systems intended for the protection of reinforcement.

This European Standard is one of a series dealing with products and systems for the protection and repair of concrete structure. It specifies a method for determining the linear shrinkage of solvent free multicomponent cold curing reactive resins.  The method is not suitable for rubber elastic and very fast curing products.

This European Standard specifies a method for the determination of the epoxy equivalent and is applicable to all epoxy compounds, for products and systems for the protection and repair of concrete structure. This European standard does not apply to the measurement of epoxide equivalent of nitrogen-containing resins.

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 resistance to water absorption of repair products and systems, as defined in EN 1504-3 .
The method is based on measuring the increase in weight due to capillary absorption of water over a fixed time interval. The weight of water absorbed is expressed as a coefficient, indicating the tendency of the specimen to imbibe water by capillary action without external pressure applied.

This standard is the third in a series of five parts to assess the thermal compatibility of repair products and systems, comprising grouts, mortars and concretes and surface protection systems, used for the repair and protection of concrete structures. The method measures the effect of thermal cycling, including wetting and drying but without de-icing salt immersion, upon surface protection and injection systems used as part of a repair product or system.

This European Standard is the fifth of a series of five parts to assess the thermal compatibility of products and systems for the repair and protection of concrete. This part is relevant only to surface protection systems, and specifies a method for determining the resistance of surface protection systems to high temperature shock.
This test method is also suitable for testing the resistance of surface protection systems against hot chemicals.

This European Standard describes a method for determining total basicity number of amines and is applicable to amine-based hardeners used in the epoxy resins.

This European Standard describes a method to record an infrared spectrum. It applies to products based on synthetic resins before their application and more particularly, in the case of two-component products, to each components separately before mixing. It also applies to emulsions of polymers (latex) that are to be mixed with hydraulic binders.

This European Standard specifies requirements for the identification, performance (including durability) and safety of structural bonding products and systems to be used for the structural bonding of strengthening materials to an existing concrete structure, including:
1)   the bonding of external plates of steel or other suitable materials (e.g. fibre reinforced composites) to the surface of a concrete structure for strengthening purposes, including the laminating of fabrics in such applications;
2)   the bonding of hardened concrete to hardened concrete, typically associated with the use of precast units in repair and strengthening;
3)   the casting of fresh concrete to hardened concrete using an adhesive bonded joint where it forms a part of the structure and is required to act compositely.
The performance requirements in this part of this European Standard may not be applicable to highly specialized applications in extreme environmental conditions, e.g. cryogenic use, nor do they cover specialized circumstances such as accidental impact, e.g. due to traffic or ice, or earthquake loading where specific performance requirements will apply.
