This European Standard specifies requirements for the identification, performance (including durability) and safety of products and systems to be used for the structural and non-structural repair of concrete structures.
This European Standard covers repair mortars and concretes, possibly used in conjunction with other products and systems, to restore and/or to replace defective concrete and to protect reinforcement, necessary to extend the service life of a concrete structure exhibiting deterioration. The fields of application covered are in accordance with ENV 1504-9 as follows:

This standard describes two methods for the determination of the total (free and bound) acid soluble chloride content of hardened concrete or mortar. This information is intended for use in estimating the risk of chloride induced corrosion of the steel reinforcement. It may be used on samples of powder obtained either by drilling or from cores or fragments removed from concrete structures or on other appropriate laboratory specimens.

This European Standard specifies an accelerated laboratory method for measuring the resistance against carbon dioxide penetration through repair products and systems, as defined in EN 1504-3 1). The method is suitable for assessing the performance of repair grouts, mortars and concretes without a protective coating system applied. The method does not measure the resistance to reduction in pH-value that may occur by absorption of other acidic gases (e.g. SO2, HCl etc.).

This part of the European Standard specifies a method for measuring the particle size distribution of the dry components of repair mortar mixes, being part of a repair product or system, as defined in prEN 1504-3, with a maximum particle size of 8 mm or 10 mm.
Part 1 does not cover particle size distribution of separate aggregates, which should be determined in accordance with the test method described in EN 933 series.
NOTE Part 2 of this Standard gives a method for granulometric analysis of fillers for polymer bonding agents.

This European Standard specifies a method for measuring the dimensional stability (i.e. the shrinkage and expansion movement) due to changes in the moisture content of hydraulic mortars or concretes (CC) or polymer hydraulic cement mortars or concretes (PCC) as defined in EN 1504-1. Two methods are proposed, namely a procedure for unrestrained movement and a procedure for restrained movement.
The provisions of the standard are applicable to grout, mortar or concrete products or systems with a maximum aggregate size of 10 mm.

This European Standard specifies a method for determining the applicability overhead of products and systems for the repair of concrete as defined in prEN 1504-3 under usual conditions.
NOTE This method can only demonstrate that products are capable of being applied overhead. It cannot take into account the possible effects of the operative's skill on site.

This European Standard specifies a method for determining the workability (or consistence) of flowing-grade hydraulic cement mortars CC, polymer modified hydraulic cement mortars PCC and polymer bound mortars PC for the protection and repair of concrete, as defined in EN 1504-1.
The method is suitable for high flow grouts or mortars that have a maximum aggregate size of 4 mm.

Normal workability concrete mixes, which can include proprietary formulations, are applied and compacted in accordance with conventional practice. The workability of these products should be assessed using the slump, VeBe or other appropriate method given in EN 206-1. The workability of conventional high flow concrete mixes should be assessed by the method of EN 12358.

This European Standard is the first of five parts to assess the thermal compatibility of repair products and systems, including grouts, mortars and concretes and surface protection systems, used for the repair and protection of concrete structures. The method measures the effect of freeze-thaw thermal shock cycling with immersion in saturated de-icing salt solution. The method is suitable for repair products and systems based on CC, PCC and PC binders and for surface protection systems.

This standard is the second 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 shock cooling (thunder-shower) from an elevated temperature. The method is suitable for repair products and systems based on CC, PCC and PC binders and for surface protection systems.

This European Standard specifies a method for determining the compressive strength of mortars and concretes for structural and non-structural repair, as defined in EN 1504-1. The method applies to all types of repair mortar and concrete with a maximum aggregate size of 8 mm. It distinguishes between mortar with hydraulic and polymer binders. Hereafter, the term mortar refers to both mortars and concretes.
