Recommendations

Over 200 RILEM Technical Recommendations have been produced by RILEM Technical Committees. Many of these recommendations have been adopted in research and practice, and are used by international standardisation bodies, as a basis for their work.

All RILEM recommendations reflect the state-of-the-art at the time of publishing. Note that these documents may be superseded later by more recent recommendations.

As chloride ions in concrete are partially bound with
the solid phases,only the so-called free chlorides are a
risk of reinforcement corrosion.However there are
experimental difficulties of an accurate measurement of
either bound and free chlorides due to:a)their relation is
not constant as it evolves with time and temperature,
b)there are no reliable analytical methods of quantifica-
tion of bound chlorides.For free chlorides,it is generally
accepted that the squeezing of hardened pastes of
concretes gives the best approximation to the chloride
ionic concentration existing in capillary pores [1-5 ].Due
to the complexity of this technique,and to its difficulty
to be applied to concrete samples,methods based on
leaching have been tried [6,7 ].
The present recommendation is the result of a
Round Robin Test on chloride analysis in concrete,car-
ried out by the Technical Committee TC 178-TMC.A
total of 20 laboratories around the world have partici-
pated in this part of the RRT making a total of 37
determinations of free chlorides in triplicate specimens
for three different chloride concentrations.
Two different methods of extraction of water soluble
chlorides from the solid sample [6 ]and [7 ]were tested,
taking as the target values those obtained by squeezing the
powdered samples by applying high pressure.It was also
decided that other methods could also be used to the
choice of each laboratory.The complete recipes and all
the results including the statistical analysis can be found
in [8 ].As a final result,the two methods proposed were
considered to be a suitable reference for extracting water
soluble chlorides.However provided that the method
given in [6 ]is easier to perform,it has been considered
to take it as the reference method for extraction of free
chlorides,and is the only one described in the present
recommendation.Experimental description of the
leaching with alkaline water method can be found in [7 ].
