Resistance to freeze-thaw cycles is an important factor for the durability of concrete. Since August 2006, new methods are introduced in a European Technical Specification CEN/TS 12390-9. This necessitates a comparative study of the test methods described in it, not only between them, but also with the methods used in Belgium. A joint prenormative research project has started as collaboration between the Cement Industry Research Centre (CRIC-OCCN), the Belgian Road Research Centre (BRRC), and the Katholieke Universiteit Leuven (KUL). This project evaluates the five different test methods and compares the results obtained on different types of concrete.
