Introduction
At present, this test method is not proposed as an European Standard (EN) but issued instead as a Technical
Specification (TS). It will remain a TS until more data and experience is forthcoming regarding the most
appropriate conditioning of specimens immediately prior to freeze-thaw cycling. Reference to the test method
reveals that three methods of conditioning are described/permitted for the two day stage between first stage
curing (to permit adequate strength development) and the freeze-thaw testing stage. This second stage
conditioning can be either complete submersion in a water bath, storage in a humidity cabinet, or continuation
of the first stage curing. Typically the latter consists of curing to prevent loss of moisture. As is stated in the
test method, it is probable that water bath curing of the test specimens is more robust than humidity cabinet
curing which in turn may be more robust than the initial first stage curing. The choice of method is deliberately
left for determination at the place of use and will depend on the type and nature of the hydraulically bound
mixture or hydraulically treated soil, the particular application and the known/expected climatic conditions.
Users of the test method are invited/encouraged to trial the different methods of second stage curing and to
provide feedback. Then and only then will consideration be given to specifying a preferred/necessary method
of second stage curing and then to the issuing of the TS as a EN.---------------------- Page: 7 ----------------------

4 Principle
Two sets of three test specimens are prepared from a hydraulically bound mixture. The moulds containing the
mixture are then placed in initial (first stage) curing conditions specified by the nature of the hydraulic
constituents and in accordance with national regulation or decision at the place of use.
On completion of the first stage curing, the two sets of test specimens (sets A and B) are removed from their
moulds and placed in a water bath or humidity cabinet or returned to the initial curing conditions, for two days
further curing (second stage).NOTE 1 Water bath curing is more robust/onerous than humidity cabinet curing which in turn may be more
robust/onerous than the initial curing condition employed. The selection therefore of the type of second stage curing
depends on the type and nature of the hydraulical...
