This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, a
18、t the latest by March 2009, and conflicting national standards shall be withdrawn at the latest by March 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or
19、 all such patent rights. It has been prepared by Sub-committee 8 “Products and systems for the protection and repair of concrete structures” (Secretariat AFNOR). This document supersedes ENV 1504-9:1997. Modifications to ENV 1504-9:1997 are: a) Status of document changed form pre-standard to standar
20、d; b) Editorial and technical modifications in those cases where necessary. This document is one part of the European Standard on “Products and systems for the protection and repair of concrete structures Definitions, requirements, quality control and evaluation of conformity”.

24、roduction Protection and repair of concrete structures require complex design work. This European Standard defines the principles for protection and repair of concrete structures which have suffered or may suffer damage or deterioration and gives guidance on the selection of products and systems whi
25、ch are appropriate for the intended use. This European Standard identifies key stages in the repair process: assessment of the condition of the structure; identification of the causes of deterioration; deciding the options for protection and repair; selection of the appropriate principle(s) of prote
26、ction and repair; selection of methods; definition of properties of products and systems; specification of maintenance requirements following protection and repair. This European Standard contains an Annex A (Informative) which provides guidance and background information on the Normative text. BS E
27、N 1504-9:2008EN 1504-9:2008 (E) 5 1 Scope This Part of EN 1504 sets out basic considerations for specification of protection and repair of reinforced and unreinforced concrete structures (including, for example, pavements, runways, floor slabs and pre-stressed structures) using products and systems
28、specified in other Parts of the EN 1504 series or any other relevant European Standard or European Technical Approval. This European Standard covers atmospherically exposed, buried and submerged structures. This European Standard includes: a) the need for inspection, testing and assessment before an
29、d after repair; b) protection from causes of defects and their repair in concrete structures. Causes of such defects may include: 1) mechanical actions, e.g. impact, overloading, movement caused by settlement, blast, vibration and seismic actions; 2) chemical and biological actions from environments
30、, e.g. sulphate attack, alkali aggregate reaction; 3) physical actions, e.g. freeze-thaw, thermal cracking, moisture movement, salt crystallisation and erosion; 4) fire damage; 5) reinforcement corrosion resulting from: i) physical loss of the protective concrete cover; ii) chemical loss of alkalini
31、ty in the protective concrete cover as a result of reaction with atmospheric carbon dioxide (carbonation); iii) chloride (or other chemical) contamination of the concrete; iv) stray electrical currents conducted or induced in the reinforcement from neighbouring electrical installations. c) repair of
32、 defects caused by inadequate design, specification or construction or use of unsuitable construction materials; d) providing the required structural capacity by: 1) replacement or addition of embedded or external reinforcement; 2) filling of cracks and voids within or between elements to ensure str
33、uctural continuity; 3) replacement or addition of concrete or whole elements; e) waterproofing as an integral part of protection and repair; f) principles and methods of protection and repair, for example those listed in Table 1. Site application is covered in Part 10 of this European Standard. Furt
34、her background information on the scope of this European Standard is given in Annex A (Informative).

General guidance is given
46、 in Annex A (informative). 4.2 Health and Safety The risks to health and safety from falling debris or local failure due to removing materials, and the effect of deterioration upon the mechanical stability of the concrete structure shall be assessed. Where the concrete structure is considered to be
47、unsafe, appropriate action shall be specified to make it safe before other protection or repair work is undertaken, taking into account any additional risks that may arise from the repair work itself. Such action may include local protection or repairs, the installation of support or other temporary
48、 works, or partial or even complete demolition. 4.3 Assessment of defects and their causes An assessment shall be made of the defects in the concrete structure, their causes, and of the ability of the concrete structure to perform its function.
