Nordic Concrete Research Workshop


There is a push for performance-based concrete design at the expense of deemed to satisfy approaches. This also pushes for more performance testing. There are several test standards that can be used to quantify concrete frost resistance, e.g. ASTM C666, ASTM C672, and CEN/TS 12390-9, where the later contains three different test methods to choose from. In addition, a number of product standards for concrete products also specify different accelerated freeze-thaw methods.

The aim of the workshop is to discuss the results of recent years’ research in relation to accelerated freeze-thaw testing of concrete. For example:

  • How well does specific methods represent field conditions?
  • Even the test principle is similar, test methods differ in specific parameters. The three test methods in CEN/TS 12390-9 (slab test, cube test, and CDF test, respectively) e.g. differ with respect to
    - duration of capillary suction prior to freeze/thaw (slab: 3 days; cube: 1 day; CDF: 7 days)
    - type of liquid used for capillary suction (slab: pure water; cube & CDF: 3% NaCl)
    - amount of freezing medium relative to test surface (slab: 3 mm; CDF: 5 mm; cube > 10 mm)
    - Temperature cycle (slab: 24 h; cube: 24 h (not identical to slab cycle); CDF: 12 h)
    How does choice of specific parameters influence the test result?
  • Are some test methods more or less favorable for concrete with supplementary cementitious materials (SCM)?
  • How can reproducibility be improved and inter-laboratory variations be limited?

The workshop is not limited to the above questions – they are only meant as inspiration. All presentations related to the over-all topic “Accelerated freeze-thaw testing of concrete” are welcome.

There will be no workshop proceedings. It is planned to submit an extensive workshop summary to the journal “Nordic Concrete Research”. All workshop presenters will be asked if they would like to co-author the summary.
