Testing hardened concrete - Part 9: Freeze-thaw resistance with de-icing salts - Scaling
SIST-TS CEN/TS 12390-9:2017

This Technical Specification describes the testing of the freeze-thaw scaling resistance of concrete both with water and with sodium chloride solution. It can be used either to compare new constituents or new concrete compositions against a constituent or a concrete composition that is known to give adequate performance in the local environment or to assess the test results against some absolute numerical values based on local experiences.
Extrapolation of test results to assess different concretes, i.e. new constituents or new concrete compositions, requires an expert evaluation.
NOTE   In some cases the test methods may not be suitable for testing special concretes e.g. high strength concrete or permeable concrete. In these cases the result needs to be treated with caution. Also, the testing methods included in this document may not identify aggregates that are subject to occasional ‘pop-outs’.
There is no established correlation between the results obtained by the three test methods. All tests will clearly identify poor and good behaviour, but they differ in their assessment of marginal behaviour. The application of different acceptance limits for test results enables assessment for different degrees of exposure severity. Change of parameters of the testing procedure may have artefacts, some of which explained in Annex A.

CEN/TR 16142:2011(Main)
Concrete - A study of the characteristic leaching behaviour of hardened concrete for use in the natural environment
SIST-TP CEN/TR 16142:2011

This Technical Report describes a method for characterising the time-dependent leaching behaviour of components from hardened concrete, for use in the natural environment.
This method specifies the procedures for determining the controlling mechanism(s) for leaching of components, their effective diffusion coefficients, in the case of diffusion-control and their cumulative release behaviour over any period of time.
This characterisation method consists of two leaching test procedures.  A potential or availability (pulverised specimen) test and a diffusion (tank) [monolithic specimen] test.
The test procedures produce leachates, the analytical procedures for which are not included in this Technical Report.
This Technical Report does not comprise a compliance method.
NOTE 1   The information obtained from the method is quantitative.  In the absence, however, of similar information for other construction materials or compliance criteria for acceptable/unacceptable performance of hardened concrete, the data obtained with neither permit a relative nor an absolute assessment of the environmental quality/compatibility of the concrete, unless, by default, in the case where leached concentrations of environmentally significant components are at, or below, their analytical limits of detection.
NOTE 2   In principle, this method could be used to characterise the leaching behaviour of hardened concrete, irrespective of the exposure conditions (e.g. natural environment, contact with drinking water etc.) which the concrete would experience in service.  It should be noted, however, that a European standard test method for the extraction/migration of mineral micropollutants is also likely to be developed by CEN/TC 164 - Water supply.
NOTE 3   Analytical procedures for determining concentrations of components in leachates and which may be suitable for the purposes of this Technical Report are being developed by CEN/TC 292 - (...)

Concrete - Release of regulated dangerous substances into soil, groundwater and surface water - Test method for new or unapproved constituents of concrete and for production concretes
SIST-TP CEN/TR 15678:2008

This document outlines three test methods.  The first is designed to test the constituents of concrete, not designated as WT products, using reference concrete matrices (control mixes and test mixes) wherein the release of (regulated) dangerous substances from the constituent under test, into soil, groundwater or surface water, can be determined.  The types of constituent which can be tested using this method are as follows:
a)   factory-made cements;
b)   aggregates;
c)   additions type I;
d)   additions type II;
e)   admixtures;
f)   polymer modifiers;
g)   fibres.
The second method, in normative Annex A, is designed to test factory made concrete products, not designated as WT products, as either test pieces sawn or cored from pre-hardened monoliths or as standard-sized moulded test pieces formed from proxy samples of fresh wet material taken from concrete used in the production of factory made items.
The third method, in informative Annex B, is designed to test concretes sampled in the fresh wet state or pre-packaged state, not officially classified as WT products, as standard-sized moulded test pieces.
All three methods produce eluates that may be used for the purposes of characterisation testing, initial type testing (ITT) or further testing (FT) of either the constituents of concrete identified in this Scope or of production concretes.

CEN/TR 196-4:2007(Main)
Methods of testing cement - Part 4: Quantitative determination of constituents
SIST-TP CEN/TR 196-4:2008

This European Technical Report describes procedures for determining the contents of most of the constituents of the cements that fall within the scope of EN 197-1.
In principle, the method described in Clause 6 applies to all cements, whatever the number and nature of their constituents, but in practice is limited to the cements identified in Table 1.
The method in clause 6 should be considered to be the method of choice and is based on a sequential selective dissolution of the cement’s constituents, generally of an unknown number, where they are not available separately for analysis at the same time as the cement.
The method of choice enables the quantitative determination (by mass) of: Portland cement clinker, blastfurnace slag, siliceous fly ash, natural pozzolans, limestone, silica fume and set regulators in cements of the types identified in Table 1. Table 1 is derived from Table 1 of EN 197-1.
NOTE 1   Where cements contain calcareous fly ash, burnt shale and/or constituents that partly contain mineral phases, similar to those of clinker, further investigation into the characteristics of those constituents will be necessary before the method can be applied.
The method of choice has limitations, as indicated earlier, and cannot be considered to be a means by which clinker content can simply be determined in isolation from any other constituent. Clinker content is determined ‘by difference’ and other constituents contain, in part, mineral phases similar to those present in clinker and can cause interferences that lead to difficulties in interpretation of the results.
Where apparently anomalous results are obtained, it is recommended that further investigations are undertaken in accordance with the procedure given in Section 6.2.5.4.
Any other method with the same objectives, and intended for use where the constituents are unavailable for separate analysis, can be considered to be an alternative to the method of choice when it is shown that, with appropr

Testing of hardened concrete - Part 19: Determination of electrical resistivity
SIST EN 12390-19:2023

This document describes two methods for measuring the electrical resistivity of concrete in water saturated conditions: the volumetric method (see 3.1.3), which is the reference method, and the surface method (see 3.1.4). The document gives the procedure to calibrate the surface method by means of the reference-volumetric method. Both methods give the same resistivity result, provided the provisions of the present document (using the Form Factor (Ff) for equivalence between them) are followed.
NOTE   The volumetric method is applicable to cast specimens or cores, while the surface method is suitable for use on cast specimens, cores and on construction sites, but not all of these applications are covered in this document.
The method can be applied to the normal range of concretes covered by current standards. It does not cover concretes containing metallic components or made with porous aggregates.
The use of resistivity to assess the potential for corrosion of reinforcement in existing structures is not specified in this document.
The use of resistivity to test cores taken from an existing structure, which require pre-conditioning by water saturation, is not covered in this document.
