What is PD CEN/TS 12390-9 - Freeze-thaw scaling resistance of concrete about?
PD CEN/TS 12390 is a series of international standards on concrete used for building construction that have the capacity to bear the structural as well as service loads that are applied to it.
PD CEN/TS 12390-9 is the ninth part of the PD CEN/TS 12390 series of documents that describes the testing of the freeze-thaw scaling resistance of concrete both with water and with sodium chloride solution.
PD CEN/TS 12390-9 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 require an expert evaluation.
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.
