National foreword

This British Standard is the English language version of EN 1504-1:1997. No existingstandard is superseded.

The UK participation in its preparation was entrusted by Technical CommitteeB/517, Concrete, to Subcommittee B/517/8, Repair and protection of concretestructures, which has the responsibility to:

aid enquirers to understand the text;

present to the responsible European committee any enquiries on theinterpretation, or proposals for change, and keep the UK interests informed;

monitor related international and European developments and promulgatethem in the UK.

A list of organizations represented on this committee can be obtained on request toits secretary.

Cross-references

The British Standards which implement international or European publicationsreferred to in this document may be found in the BSI Standards Catalogue under thesection entitled International Standards Correspondence Index, or by using theFind facility of the BSI Standards Electronic Catalogue.

A British Standard does not purport to include all the necessary provisions of acontract. Users of British Standards are responsible for their correct application.

Compliance with a British Standard does not of itself confer immunityfrom legal obligations.

Foreword

This European Standard has been prepared byTechnical Committee CEN/TC 104, Concrete(performance, production, placing and compliancecriteria), the Secretariat of which is held by DIN.

This European Standard shall be given the status of anational standard, either by publication of an identicaltext or by endorsement, at the latest by July 1998, andconflicting national standards shall be withdrawn atthe latest by July 1998.

This European Standard is part of a series of standardsdealing with the general considerations related to theproducts and systems for the repair and protection ofconcrete structures.

The other parts of this standard are:

prEN 1504-2, Products and systems for the protectionand repair of concrete structures Definitions,requirements, quality control and evaluation ofconformity Part 2: Surface protection systems.

3.2 main categories of products and systems

3.2.1

surface protection products and systems

products and systems which, when applied, improvethe durability of concrete and reinforced concretestructures

3.2.2

non-structural repair products and systems

products and systems which, when applied on aconcrete surface, restore the geometric or aestheticaspect of the structure

3.2.3

structural repair products and systems

products and systems applied to a concrete structure,to replace defective concrete and to restore structuralintegrity and durability

3.2.4

products and systems for bonding

products and systems applied to concrete to provide adurable structural bond to additional applied material

3.2.5

products and systems for injection

products and systems which, when injected into aconcrete structure, restore the structural integrityand/or durability

3.2.6

products and systems for anchoring

products and systems which:

anchor reinforcement into concrete to giveadequate structural behaviour;

fill cavities in order to ensure a continuitybetween steel and concrete elements

3.2.7

binders which generally consist of two components, areactive polymer base and a hardener or catalyst, andwhich cure at ambient temperature. Additives(see 3.3.8) may also be added

NOTE 1 Ambient moisture vapour may act as thehardener/catalyst in some systems.

NOTE 2 Usual binders are for example:

epoxies; polyesters; cross-linkable acrylics; one or two-component polyurethanes.

3.3.6

admixtures

Admixtures are defined in prEN 934-2.

3.3.7

additions

finely divided inorganic materials that may be added torepair products in order to improve certain propertiesor to achieve special properties

There are two types of additions:

nearly inert additions (type I); and

pozzolanic or latent hydraulic additions (type II).

3.3.8

additives for reactive polymer

products other than admixtures and additions whichgive the repair product specific properties

NOTE Usual additives are for example:

plasticizers;

flexibilizers;

accelerators;

retarders;

materials which regulate the rheology;

pigments;

fillers.

3.3.9

additives for hydraulic binders

products which are added with hydraulic binder togive specific properties and which are not covered byadmixtures and additions

3.3.10

hydraulic mortars and hydraulic concretes (CC)

mortars and concretes based on a hydraulic binderwhich is blended together with graded aggregates andmay include admixtures and additions and which,when mixed with water, set by a hydration reaction

3.3.11

polymer hydraulic cement mortars or concretes(PCC)

hydraulic mortars/concretes modified by the additionof polymer

NOTE Polymers generally used include:

acrylic, methacrylate or modified acrylic resins asredispersible powders or aqueous dispersions; vinyl mono-, co- and ter-polymers as redispersible powdersor aqueous dispersions; styrene butadiene rubber as aqueous dispersions only; natural rubber latices; epoxies.
