DIN EN 1504-9:2008-11 EN 1504-9:2008 (E) 4 Introduction Protection and repair of concrete structures require complex design work. This European Standard defines the principles f

26、or 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 which are appropriate for the intended use. This European Standard identifies key stages in the repair process: assessment of the cond

27、ition of the structure; identification of the causes of deterioration; deciding the options for protection and repair; selection of the appropriate principle(s) of protection and repair; selection of methods; definition of properties of products and systems; specification of maintenance requirements

28、 following protection and repair. This European Standard contains an Annex A (Informative) which provides guidance and background information on the Normative text. DIN EN 1504-9:2008-11 EN 1504-9:2008 (E) 5 1 Scope This Part of EN 1504 sets out basic considerations for specification of protection a

29、nd repair of reinforced and unreinforced concrete structures (including, for example, pavements, runways, floor slabs and pre-stressed structures) using products and systems specified in other Parts of the EN 1504 series or any other relevant European Standard or European Technical Approval. This Eu

30、ropean Standard covers atmospherically exposed, buried and submerged structures. This European Standard includes: a) the need for inspection, testing and assessment before and after repair; b) protection from causes of defects and their repair in concrete structures. Causes of such defects may inclu

31、de: 1) mechanical actions, e.g. impact, overloading, movement caused by settlement, blast, vibration and seismic actions; 2) chemical and biological actions from environments, e.g. sulphate attack, alkali aggregate reaction; 3) physical actions, e.g. freeze-thaw, thermal cracking, moisture movement,

32、 salt crystallisation and erosion; 4) fire damage; 5) reinforcement corrosion resulting from: i) physical loss of the protective concrete cover; ii) chemical loss of alkalinity in the protective concrete cover as a result of reaction with atmospheric carbon dioxide (carbonation); iii) chloride (or o

33、ther chemical) contamination of the concrete; iv) stray electrical currents conducted or induced in the reinforcement from neighbouring electrical installations. c) repair of defects caused by inadequate design, specification or construction or use of unsuitable construction materials; d) providing

34、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 structural continuity; 3) replacement or addition of concrete or whole elements; e) waterproofing as an integral part of protecti

35、on 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.

47、repair 4.1 General Clause 4 outlines procedures that shall be undertaken to assess the current condition of a concrete structure before protection and repair. General guidance is given in Annex A (informative). 4.2 Health and Safety The risks to health and safety from falling debris or local failure

48、 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 unsafe, appropriate action shall be specified to make it safe before other protection or repair work is undertaken,

49、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 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.
