DIN CEN/TR 16563 (DIN SPEC 18097):2014-04 CEN/TR 16563:2013 (E) 4 Introduction (1) The Equivalent Durability Procedure
15、 (EDP) is a scheme that builds on the traditional method of ensuring durable concrete by specifying established limiting values in terms of maximum w/c ratio, minimum cement content etc. Essentially, a reference value is determined and a candidate concrete can be confirmed as being of equivalent per
16、formance where testing and other appropriate assessments are made to demonstrate equivalent performance with this reference value or reference concrete. The reference value is determined based on concretes that satisfy fully the limiting value specification valid in the place of use and are represen
17、tative of concretes that are successfully used in the local environment as providing a satisfactory service-life. To be considered a viable alternative, the proposed candidate concrete need to have a test performance that equals, or is better than, the reference value when tested by the same method
18、and at the same age as used to establish the reference performance. Such a comparison leads to equivalent performance in the test at the age of testing. As the rate of improvement in resistance is not constant between concretes, the reference value will be appropriate for the constituents used in th
19、e candidate concrete. (2) No relatively short-term laboratory test will give a precise quantitative indication of real performance of in-situ concrete. One reason for this is that concrete will continue to gain strength and resistance to the permeation of aggressive species in most natural environme
20、nts, e.g. concrete will increase its resistance to the permeation of chloride ions with time, albeit at an ever decreasing rate. Such changes in performance over time, collectively called ageing effects, need to be taken into account when determining if the candidate concrete will provides an equiva
21、lent durability over the service-life. NOTE With respect to durability, the changes can be positive or negative. For example, reaction with seawater may result in a surface layer that increasingly inhibits the penetration of chloride ions and hence improve durability. On the other hand, carbonation
22、of concrete may release chlorides ions that were previously bound into the hydrate structure and, as these are then free to migrate towards any reinforcement, the durability may be reduced. (3) Some CEN members have established national EDP type procedures which provide results that are likely to be
23、 reasonably indicative of in-situ performance or procedures whereby equivalent durability may be safely assumed for defined sets of materials. See Annex A to Annex H for some examples. (4) This Technical Report provides guidance to National Standards Bodies who want to establish an EDP in their nati
24、onal provisions to EN 206. DIN CEN/TR 16563 (DIN SPEC 18097):2014-04 CEN/TR 16563:2013 (E) 5 1 Scope This Technical Report sets out the principles of the equivalent durability procedure.

39、ation together with the time evolution of cement phase microstructure, its interaction with the penetration species and, in certain cases, of concrete surface changes due to its direct interaction with the external environment Note 1 to entry: Example for interaction with the penetration species is:
40、 chloride binding. Note 2 to entry: Example for direct interaction with external environment is: a skin effect when concrete is exposed to seawater. 3.2 candidate concrete concrete comprising a closely defined set of constituents under investigation to determine the mix proportions that are likely t
41、o provide a durability performance equal to or greater than a reference value or reference concrete for the selected exposure class DIN CEN/TR 16563 (DIN SPEC 18097):2014-04 CEN/TR 16563:2013 (E) 7 3.3 equivalent durability related test performance procedure based on testing, by which a candidate co
42、ncrete is shown to have equal or better performance than a reference value - when checked for the performance criteria linked to a selected exposure class Note 1 to entry: The process includes the definition of the performance value, testing the candidate concrete with a performance test at a specif
43、ied age, and comparing it with the appropriate reference value of performance or the performance of the reference concrete at the same age. 3.4 reference concrete concrete where all the constituents and mix proportions are prescribed, conforming to the EN 206 provisions valid in the place of use and
44、 representative of the national/local experience in the defined exposure class. 3.5 reference value value that the candidate concrete has to achieve or be better than and which is determined from either: a) a previously established value where this has been established from any combination of testin
45、g or service-life modelling; b) tests on the reference concrete; c) a value selected from the range of values resulting from testing concretes that conform to the provisions valid in the place of use and is representative of the national/local experience in the defined exposure class 4 Principle (1)
46、 The equivalent durability procedure (EDP) is a scheme for establishing conformity to EN 206 of concrete compositions that deviate from the limiting value criteria valid in the place of use. Durability testing to meet defined criteria is undertaken and this leads to a limiting value specification th
47、at is valid only for the constituents used in the candidate concrete. This procedure only applies to concrete compositions that comprise constituents (natural, manufactured or recycled) covered by European technical specifications referred to in EN 206 or provisions valid in the place of use. (2) Th
48、e procedure is applicable to any exposure class, but in practice it is limited to exposure classes where there are agreed standardized test methods (see 5.2). The application of the EDP is not appropriate for the X0 exposure class, as there are no environmental conditions that are aggressive to conc
49、rete or reinforcement. (3) The EDP is to determine the equivalence of a candidate concrete used with the same minimum cover in the same exposure classes and intended working life as those appropriate for the reference value. (4) The EDP includes at least three parts: Part 1: The setting of a reference value or the prescription of a reference concrete from which a reference value can be determined; Part 2: Initial testing and assessment of the candidate concrete to establish
