Overview

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, that is 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. In case of justified modifications of the test parameters, precautions might apply. Some alternative applications are described in Annex A. The standard differs from DIN CEN/TS 12390-9:2006-08 as follows: - the normative references in Clause 2 have been updated; - a specification for the measurement of the CO2 content of the air in the climatic room or chamber has been included in Clauses 5, 6 and 7 (for all test methods); - the alternative applications have been specified in detail in Annex A; - a technical specification has been included in Annex B; - the references have been updated in the bibliographies. Working Committee NA 005-07-13 AA "Zement, SpA zu Teilbereichen von CEN/TC 51 und ISO/TC 74" ("Cement, Mirror Committee of parts of CEN/TC 51 and ISO/TC 74") at DIN Standards Committee Building and Civil Engineering (NABau) is responsible for the German collaboration.
